Mirror Imp/ Fire Imp crash on kill

I'm getting a repeated crash when killing imps, even after polymorphing amd killing them the game either hard crashes or freezes. Any remedies for this?

Many thanks,
Liam

Sorry about that, the imps are not correctly removed after death in the current version. There is an as of yet unmerged fix here.

Thanks for the reply, and all the hard work!

What do mirror imps do?
