this happened to me too

---UPDATE---
If you kill ALL the skeletons before the Lich the game does not crash/freeze.


I had this happen to me. I killed the Lich before i killed any of the skeletons. The game freezes, never shows a crash.

There are about 1000 more lines of the skeletons being dead i didn't post.

and me.

Lich vs Lich, I got massacred.

then my Shadow teleported in and out while my Monk takes the killing blow with his flying kick and lightning strike, game freeze

I really don't want to fight two giant skeletons and a dozen Skels.

ps Love this mod, battles are crazy fun. three hour demon incursion, three demons bouncing around like pinballs, everyone in hospital except my undead. lol, crying until I laught

This bug should be fixed in the latest patch (v2.6.2.8).
