Rollback?!

Season Eleven, Event 52: 1 Hour Descent

Me and several other players got a rollback on this event.... What even....
i was just about to enter a new area when i got dc'd. Logged back in and i had to start all the way back from the beginning of that particular dungeon, also the map had been reset so i could not see anything and had to re-explore the map once again....

I think that is what happens in those races anyway :P

Rollback is true
People even died for no reason
