I have been using GRSS for a while now and have not had any problems other than small issues and user error. However last night we completed Karazhan and moved onto ZA where we downed the first boss. The ZA Boss did not register as a raid and there was no information about who was there etc.
Do I need to stop upload data and purge before I move onto another instance? Last night GRSS also only recorded 2 out of the 4 Kara bosses yet all the loot was still recorded.
I notice there is still no ZA events in the Raid Progression section.
