Unfortunately I didn't get a screenshot, but yesterday I was doing Ice Caves of Sorrow with a party of 7 other people... somewhere in the beginning one left, so now we're down to 7 total, then the whole rest of the mission we're TEARING through, no problem at all!... then, once we get to the very end with one mob and boss are standing between us and the finish-line, something stupid happens and I'm still not even quite sure what, but somehow we kill everything except the dwarf boss, and then we all die except for Evenia and one monk who is standing a few yards behind the combat, evidently AFK... we all sat there for like 20 minutes (well, actually I went to grab something to eat at some point) yelling at him to wake up and revive somebody while Evenia and the dwarf boss just duked it out, getting nowhere on eachother. Then, just to rub it in, my ISP died for a few minutes, so I have no idea if they ever finished the mission or not.
On the bright side, I came back with henchies and did it with no trouble at all!
