They were primarily added by a modder. I fixed the severe issues with them, but adding random generated advisors and other things like that require more effort than I have time to spend at the moment.
Ah okay, thanks for the clarification. It's not really a big deal and I understand that there are more pressing issues right now. It would be nice however if we could see this being added in the future.

Some other things I found out during my Israel campaign and subsequent PRC campaign:
- When Ukraine exists the USSR will still claim Bessarabia. This results in quite a bit of bordergore, because the USSR does not border Romania anymore. It would be better if this National Focus has a 'has a direct border with Bessarabia' check if that's possible.
- Whilst playing as the PRC my friend, who was playing as the USSR, wanted to get Trotsky in power. He did not do the purges and the civil war fired. Because of our war with Japan however, Russia got invited into the Axis. Now we have to kill the entire Axis before Trotsky can remove his 'Permanent Revolutionary' trait and become useful. The treshold for Russia joining a war should go up because this is an internal civil war. It has nothing to do with international factions and stuff like the 'Chinese Reclamation of Bejing' and should not be treated as such. Buffs for Trotsky will have a high chance to be useless otherwise, as long as the main prerequisite is that the USSR needs to be at peace in order for them to take effect. (I can understand that opinions about this differ, this is just how I feel about the subject.)
- When we declared the war on Japan they immediately joined the Axis. Germany and Italy then started to do tons of naval invasions near Vladivostok because they didn't have a real border with the USSR. (it was '38, Poland was still save and sound). The Germans in particular managed to lose 500k troops in a few months in hopeless pockets because of this. This is pure suicide, plain and simple, and should be avoided by the AI at all costs. The conflict between Japan and China should remain as seperate as possible from the conflicts between Germany/Italy and the rest of Europe. Now Germany has wasted a huge swath of its army, but it is still going to attack Poland, France and the USSR on the Western Border as soon as it connects. I am afraid that they never manage to deal with these losses in time and that this will be an easy victory for us/the allies.
- The same goes for the allies. In my Israel campaign the Allies managed to lose 2 million men total against 10k of mine, just by suiciding day in, day out, on the beaches of Alexandria/Tel Aviv. Invasions really need to be toned down. Not only am I not able to move a huge part of my army because they are quite literally stuck (thanks to day in, day out of 1 division landings), the allies are also losing huge amounts of equipment and manpower in these suicide runs effectively rendering them unable to do anything about Germany which is currently taking over the world. Either the AI should focus on 'big' invasions which fire at the same time, or they should just not do it as often as they do now. The invasion 'horn' is also starting to really annoy me now so that's also meh

Hope this information helps.
