Multiplayer bugs

[Demonspoon]

when I played my first multiplayer game some wierd stuff happened. Firstly, in Irenicus' dungeon the genie who wants his flask, Malaaq, appeared on the U-turn path to the Duegar, the yellowy one. I talked to him and he responded as he normally does when you meet him in the elemental plane of air. When I went to the plane he was there again and i got the quest twice, though it only got finished once. Also, after witnessing the cult of the eyeless initial encounter I couldn't be bothered talking to Oisig so i just left. In the Docks, I found like 5 High Watcher Oisigs standing next to each other and later on found another one in the sewers under the Copper Coronet. The genie thing has happened a few times but only in multiplayer. Does anyone know why?
