Quote from AnadaleI had the same problems as Calest yesterday on Saurfang. Here is the scenario:
1. Fight begins, everything is OK, cooldown bars are running
2. Just after first adds I get DC
3. When I get back online DXE resyncs, but now I have two bars with adds cooldowns
4. As soon as next adds come into play I get another DC
5. Rinse, repeat.
At the end I had to disable DXE to be able to continue the fight. I want to mention that it was the first time I'd encountered such a problem - everything was OK last week.
I, also, had this last night on heroic Saurfang and was running the most recent alpha at that time (v477-90-gedda33b). I changed back to the most recent release (v477) and had no other disconnect issues. Everything is fine up until adds show up. Additionally, we were doing a regular 10-man to look at AVR: Encounters and had the same issues on Lady Deathwhisper. Everything was fine until the first adds spawned.
I'll try again tonight since I see you have released two more alphas in the past 24 hours though I'm not sure if you did anything that would have fixed what could have been causing this disconnect.
