Has anyone else encountered the glitch with Janus Hassildor (Count of Skingrad) whereby you can repeatedly click on the 'reward' topic of conversation and get a levelled amount of gold each time? It relates to the Cure for Vampirism quest.

Having completed the Allies for Bruma quest, I went to find him but had no marker on my map, so I trespassed my way to his room and woke him up to fleece him of an absurd amount of money by exploiting this glitch.

Yes, it is http://www.uesp.net/wiki/Oblivion:Vampire_Cure#Bugs, it's fixed in 1.1.511 patch
