The last days a lot of players are complaining serious lags, throw outs and almost unplayable areas.
To me it occur today at 7am, 200 other players in the server.... festival in Thorins Hall, could not beat, multiple times for 10-15 seconds the command was active but not executed. The NPC did not react, but the hint said "already activated". We were 3 player there, but each had to wait seconds after the other get the quest from the NPC to be able to interact with him...

very sad about the history of these issues
