I at first thought it was being cause by interactions, but I removed those and it still crashes consistently. There is a very strong correlation between increasing the number of megabeasts and how early worldgen crashes. If I have 150 megabeast caves, it usually makes it through year 250. If I have 300, it rarely makes it past 10.
This makes no sense. I've compared the raws over and over again to other megabeasts and I don't know what I've done that's causing it. I thought it might be related to breeding during worldgen or something, but rocs and I believe dragons do this without problems. I've successfully genned worlds with this megabeast before, but it's a real crapshoot and is a total pain. It has to have something to do with them killing something, being killed, breeding, or something, but I cannot for the life of me figure out what.
It's also frustrating that these are getting killed by what appears to be mooks in worldgen. This despite having a magical shield as hard as iron covering them and only receiving 3/4 of impact damage, on top of being very large and naturally skilled in fighting. I'm starting to think there's little I can do about that.
Edit: I added the [LAIR] tag and now it appears to be working for this particular attempt. Surely that's not the reason?
