Have a WU with 200+ hours of work done on it, don't remember the percentage it said was complete, but I suspended work on everything. When I resumed everything, this WU went back to 0%. As a comparison, another WU has 145 hours of work and is at 42%. BOINC has paused these tasks numerous times without any problems.

And if it adds anything else, looking at the task manager, it seems like when suspending, it didn't suspend the two tasks completely and they were still running, so in a sense, they were both running twice. Which makes sense why my temps were so high when I resumed everything.
Is there anything I should be looking for to get that progress back or is there a risk the results they both will return will be bad? I'd rather abort than wait the 200+ more hours to complete to have them return bad results....
