Good game but one major annoying problem!!

I definitely love this game!! Otherwise I wouldnt have played it till archmage difficulty. However, if I hadnt, I wouldnt have discovered this issue. When facing the Unsummonable (before Solomon Dark on Archmage difficulty), right before I defeat him my game crashes EVERY SINGLE TIME!! I get so close so this bug is extremely annoying. Please fix soon!!!
