Description
[3.7.4 (b646)] Pre-FTLs mechanics break if they have a nuclear war after you've already established diplomacy with them, and some other pre-FTL bugs.

Game Version
Canis Minor v3.7.4

What version do you use?
Steam

What expansions do you have installed?
All except Toxoids.

Do you have mods enabled?
Yes
(Only mod is the test branch of the Storm Cluster MODJAM2022 crisis, which isn't going to do anything until midgame and hasn't thrown anything to error.log besides the two expected overwrites.)

Please explain your issue is in as much detail as possible.
I established diplomatic relations with a Machine Age pre-FTL civilization, thanks to a rogue scientist setting himself up as a god and providing tech. They eventually fired the event where they nuke themselves back into the stone age and become completely unaware, but this didn't cancel any of the diplomatic interactions that are only available to contacted pre-FTLs or fully reset my observation outpost.

• Neither the agreement to provide societal guidance nor the commercial pact I had with them was canceled, and they continue to cost me 0.1 monthly influence.
  • The commercial pact does stop causing the observation post to produce resources.
  • The envoy I had improving relations with them remained assigned, and checking the opinion tooltip in the Contacts tab shows that they're still successfully increasing opinion each month.
• Additionally, the observation post's observation type/stance doesn't get set to anything, so it doesn't produce any research until you notice and go set one manually.
• I also retained my 49% infiltration spy network, which seems weird when the society I infiltrated is gone.
• While global nuclear war could reasonably destroy their entire tech base and the expertise required to recreate it, I don't think it makes sense that all the survivors of a fully aware society actively engaging with and receiving societal guidance from aliens suffers instantaneous collective amnesia of the general knowledge that the people they were talking to yesterday exist.

Issues remain after month ticks over.

Timeline, with probable bugs highlighted:

1. (2232.06.24.sav) Rogue scientist establishes himself as god over Fanatic Xenophile Spiritualist Pre-FTL, providing tech bringing them to the machine age. The event option tooltips say this will increase their awareness by 100, but it actually sets them to 90 which is only +71.
2. I successfully extract the rogue scientist after he starts trying to conquer the world, and am warned that this may negatively them in some way (the event text gave me the impression that it meant diplomatically).
3. Pre-FTL ticks up to 100% awareness and establishes contact, being perfectly happy to interact with me.
   • There seem to be no opinion modifiers or dialogue changes from the extraction mission, maybe they didn't realize I did that?
4. I notice that an AI empire I traded communications to starts is giving them societal guidance and has a commercial pact with them. I think this actually causes the observation post to start producing energy for me, at least according to the outliner.
   • I don't think it makes sense that they can do this without asking my permission or even notifying me, since they'd need be be working through my observation outpost.
   • And honestly there should be an option to only trade contact with other regular empires; I'm trying to make everyone in the galaxy aware of the fanatic purifier neighboring me, not hand them access to my pre-FTLs and mercenaries.
5. I assign an envoy to improve relations, and begin societal guidance (I'm Xenophile + Materialist + Pacifist) and form a commercial pact with them myself once their opinion increases enough.
   • At this point the meddling AI has ended their diplomacy with my pre-FTL on their own.
6. Societal Guidance successfully changes their ethics from Fanatic Xenophile + Spiritualist to Fanatic Xenophile + Pacifist.
7. Global religious war breaks out due to the abduction of their 'god'! Ethics shift to Fanatic Spiritualist + Xenophile.
   • This feels a bit weird since they're pacifists, and not spiritualists anymore.
8. (2241.08.28 nuclear war after rollback.sav) The civilization destroys itself with nuclear war while still in the Machine Age. Is it also a bug that they nuked themselves before reaching the Atomic Age?
9. (2241.10.02 month after nukes.sav) Post first contact diplomacy persists with the 0 awareness Stone Age civilization.

Steps to reproduce the issue.
(Main issue)
1. Establish diplomacy with an advanced pre-FTL civilization.
2. Form a diplomatic agreement to offer societal guidance, a commercial pact, and/or
3. Wait until they trigger the nuclear war event.
4. Those diplo agreements remain in place and continue to drain influence, and the envoy remains assigned and continues to improve opinion.

"autosave_2241.07.01.sav" is most recent autosave from before the nuclear war.
"2241.10.02 month after nukes.sav" is from the month immediately after the war, which I waited for to see if the diplo issues would update and auto-fix after the month rolled over.
"2241.08.28 nuclear war after rollback.sav" is from me rolling back to the autosave and fast-forwarding until they nuked themselves again (about a month earlier this time, but same outcome).
"2232.06.24.sav" has the rogue scientist consolodates pwoer event.

Oh, and this didn't abort the ongoing New World Order situation. I guess the charismatic leader seeking global unification and the plucky rebels survived the end of the world, and are now duking it out with sticks and stones?

Edited the report to attach error.log, which contains the following lines:

[02:54:29][eventscope.cpp:2097]: destroy_situation/abort_situation = <situation>: Unable to resolve situation from 'from' (country scope) at  file: events/first_contact_dlc_situation_events.txt line: 82
[05:32:26][effect_impl.cpp:19148]: set_fleet_stance effect is trying to set a stance that is not supported by this fleet.  file: events/colony_events_1.txt line: 4122

Looks like the game at least tried to abort the New World Order situation and maybe tried to reset the observation stance, but failed?

Also, the pre-FTL country still has the following flags after the stone age reset:

Flags:
 fircon_1325_fired
 StoryFirst
 first_alien_life
 Story5
 first_contact_protocol_event_happened
 stone_age
 recently_advanced
 steam_age_pops
 observation_100_fired
 pre_ftl_initiating_contact
 reached_full_awareness_once
 first_contact_completed0
 recent_comms_timed
 freeport_flag
 preftl_societal_enlightenment_pact_with0

Some of these like preftl_societal_enlightenment_pact_with0 and steam_age_pops seem like maybe they should've been cleared, although I haven't searched through the script files to see exactly what they do.

Update from 25 years on: The "Is there Life In There?" fired for this pre-FTL (currently Stone Age w/ Low Awareness), giving me options involving direct communication despite not being able to reveal my presence. I'm not sure if this was able to trigger because I still have an active Societal Guidance with them, or for some other reason related to being reset to the stone age after being contacted.

Other misc. pre-FTL bugs I've noticed:

• I don't have enough intel to see how many pops they have in the diplomacy interface despite being able to get the number from the planetview.
• Their pops are 50% Authoritarian and 50% Fanatic Authoritarian, and their government is Fanatic Authoritarian & Spiritualist.
• generate_pre_ftl_hive_on_planet doesn't change the Ocean Paradise planet modifier into the hive version that gives stability instead of happiness.
• The planet deficit tooltip for the pre-FTL hive mind on Neddum I says they're spending 4 minerals a month on Artisan upkeep. The factory drone job must be miscategorized as artisans instead of metallurgists.
