So, RoS has partisan tasks which have an unlimited time to complete. They are shared tasks, for 1-6 players. The shit isn't unlimited! I have found that they disappear after 24 hours. I have done half of a task and come back the next day to finish and it will have been gone after working on it off and on a few times that day. Today, the fucking task disappeared while I was doing it. I had 8 mobs of the required 10 killed for the win and it just disappeared! So, if you think you are going to work on a shared task with unlimited time over the course of a couple days, piss off! It ain't going to happen. Needless to say, I've sent in several colorful bug reports.
You have been warned!
