I'm currently playing a game that I saved last night. I noticed after looking in my inventory that I no longer have my Horadric Lutefisk cube. I am 100% positive that I had one last night
One more bug... I was just able to kick a steamy golem (using flying buffalo technique) to the other side of a locked door. The mob's back was to the door. Probably the door should have stopped him, or the door should have been broken through.
Follow up: just found another cube on level 4 in a barrel . It still is a bug, I'm just a lot less frustrated by it now.
