Which mutant? The mutant in the Well in the Imp Town? Where you rescue that kid and find the battlefield key? That mutant didn't drop anything for me and i'm now almost at the end of Act II (2 BFs and 1 main Q left).
Does it mean i'm screwed? Should I do file swapping? With the fact that also all of a sudden ACTII BF monsters stopped attacking (they just stand still) and that I can't get the rock dialogue to open entrance to the cave up, I feel like i should just stop playing the game... with this many bugs it's just not the worth the effort...
And yes, I have the patch installed.
