hey, i have a bug in last mission. i start playing and everything is fine for a period of time but than i can't cast imps anymore(i think it is, when i they get upgraded by research), also i cant put gold into the dungeon-heart, so i cant save the 16000 gold. and also the gold-room isn't working right sometimes. so the imps put in the gold in strange position, they just leave kind of 9 fields blank(always the same 9 fields. i can take the gold and put it on these fields, than it is saved on them, but the imps dont realize it right and never put the gold in there. i will try out if is a bug caused by imps or by the game, so i try out the money-cheat. i give feedback if i've done it. very nice campaign, but the first maps are very big, with big fields of unbreakable stone. but works fine and is not easy. the mission were you have to impress the one keeper and kill the other 2 keepers. god, thats a tough one, i had to find all keepers first and its freaking hard to kill the first keeper before she does, but i found easy way to eliminate her or his(i think it was a woman) monsters.
even possible if you open your dungeon to the water.
