Happens in prime time when servers are overloaded.
I joined Vivec on my warden and went to take a keep with a group, we went inside and start to kill enemy players, my quest for kill enemy sorcerers went from 9/20 to 17/20,
We fought there for like 10 minutes, and all of the sudden everything around me froze, i got disconnected after a minute, and when i joined the game again my Character was at the Base, and my kill enemy sorcerers quest was back to 9/20 and my potions amount was the same as before i went in to battle.
This happens twice this week, strange disconnects in prime time and my character progress rolling back with 5-15 minutes !
