I know that if you disable swallowers that the AI will STILL get Starship Dissembler Guardians.
I've not yet been able to find a setup where I can reproduce that bug (the AI unlocking a swallowing unit despite the toggle), or swallowing units being picked for exos in such a case, etc. I guess I can give it another look this week.
Ok, I will see what I can do to make one. I no longer have internet at home, so it may be some time before I can produce the save, but I will do what I can.
Edit: I find that I run in to it almost every game. But I run FS games only with multiple exo sources, and my AIP gets into quadruple digits without counting reduction. However, it is not always at the end that see them. Sometimes its when I'm only in the 200 total AIP ranges that they start to show up.
