Description
AI Empires Getting Aquatic Trait with Non-Ocean Habitability Preference

Game Version
Herbert 3.2.2 (abcc)

What version do you use?
Steam

What expansions do you have installed?


Do you have mods enabled?
Yes

Please explain your issue is in as much detail as possible.
I acquired pops from an AI that have the Aquatic Trait yet have Arid Preference. This should be incompatible for players creating empires, but the AI can somehow pick the Aquatic Trait even with non-ocean preferences.

Steps to reproduce the issue.
Create a new game with AI empires and check if any species has the Aquatic Trait with non-Ocean preferences.

Its either xenocompability or one of those events, which changes the habitability to that of the planet the pops currently live in, causing those shenanigans.

I know Evolutionary Mastery lets you add the Aquatic trait to species without Ocean Preference. This is probably not intended behavior.

I already reported this here. Can confirm it happens with randomly-generated empires.

The AI empire's three homeworlds were arid, so I'm guessing it's not because of Glandular Acclimation.

As far as I know, the AI Empire didn't pick genetic ascension perks. The psionic trait was because I assimilated them into my empire.

Was it a lost colony origin causing this? The ascended ai empire created by that often causes to have weird habitability settinngs.

Nope. The species' founding empire has Syncretic Evolution as its origin.

I've seen it happen with Prosperous Unification and Common Ground empires. I don't think origin ties into it.
