First off, this mod is amazing. All the work put into must have taken a small eternity.
I have hit a couple of snags with it though. I'm getting crashes when I possess certain enemies. Or rather, when I select them. I can possess Star Gods just fine, but every time I go to actually use one, it's an instant crash. A similar thing happens when I possess Beastmasters, but in this case it's only a 50/50.
In addition, when I attack a crashed gunship, there's about a 25% chance I'll get a crash (this one has an error message. M_vector or something like that). It's just with gunships, no other vessel, so far as I can tell.
Finally, this isn't a bug, but what do I have to do to research live Star Gods and plasma weapons? I've run out of things to research, and I'm not totally sure what I should focus on to continue making progress.
