The log seems to have stopped before the error in screenshot #2, which is what was actually helpful. Turns out, insectoids probably can't be turned into wild men. I'll add a check somewhere so that hopefully this doesn't happen again.

Btw I don't get a notification when a new discussion starts, so best also leave a comment too. Thanks for the bug report!

Oh ok, I wasn't really in a rush, and didn't know where bug reports go so this happened, you can close it if you want now.

Would've been cool (and rather fitting) for the insectoids to get the "burning men" raid
