All of that aside, sweet dungeon. Nice atmosphere. Quite enjoyed the romp, even if my weapon and armor repair bill is going to be astronomical.
oddly enough i didn't notice these bugs (the spiders didn't even hit me, i'm good at evading blows, spells & arrows to a lesser extent), i didn't have too much trouble with the dungeon either. it was quite hard, however not... um, overdone. i guess that's the word i'm looking for. you want hard, try escorting the priests through the shadowfang keep area, with extra werewolves as part of legends from the north & extra werewolf spawns from curse of hircine, that was crazy hard. (took me like 9 tries)
