Durlag's Tower bugged?

[Larry]

Spoilers.



So i'm at the very bottom of the tower, level 4. I've done everything, cleared every room and visited the "Warded Throne Room." When I clicked on the throne I was warped for a second time to the riddle room(Circular room with four stone golems which ask you riddles). I answered him right(Third option) and got teleported to the beginning of the level right beside the spirit/shade of Durlag Trollkiller. When I speak with him he says the same crap he said the first time I visited the riddle room and passed the test(Where you're asked three questions about the history of the family). I go north to the shade of his wife and all she offers is a teleport out of the castle. To the Southeast of her is a fake wall that can't be opened... Apparently this leads to the "Throne Room" where the Demon Knight is... Thing is, it won't open. I have all ward stones, I passed all riddles, everything. Has the game bugged out on me or am I missing something here?

Help! :'(

Nevermind... Turns out I need to visit it three times and I have to click on a bed with zero indication as to having to do that for the third and final riddle... Seen some of this happen a few times in Durlag's tower, not so much riddles as blind luck or crap you need a guide for(Thanks be the internet, eh?) take level 2 for instance, you have to place each wardstone in the coloured target dummies then you have to attack the middle target dummy. Very, very, very specific actions required to pass through and there's no indication of this at all.
