[OPEN] Game crash: "Sending/Accepting invite on adventure"

Short description:
The game crashes or automatically reloads when accepting an invite on an adventure. It takes a while before the game crashes, the first hint is that the adventure doesn't show immediately. For the players experiencing this bug it happens almost every time they accept an invite. It also happens when you send an invite or accept loot, but those crashes are a lot less frequent. It doesn't seem to affect all players. Players reporting it have all been playing before July 2012.

I am regularly affected by this bug.

Further information.

Possible link: In the adventure before the adventure you accept to cause crash, the adventure does not disappear. When you go to the adventure it gives message "adventure zone ended" or similar.

Possible workaround, by getting someone to send you a trade it "kickstarts the adventure popping up" success rates vary between 25% and 75%
