Area and Coordinates:
The 90k comes in heavy situations of lag at different places (mostly Timeout)

Solo

NPC Name:
no NPC's involved

Monster Name:

In-Game Time:
Happend several times during gameplay.

Steps (self measured traffic):
I had permantly lags between 1-10 seconds. The lag comes from server issues or more precisely from jammed Packages in a regular TCP session. Mostly one package isnt transmitted correctly and have to be retransmitted. All Other Packages during this time are stored in a local buffer. Finally after 1-10 seconds the missing package comes in and the buffer will be released. All actions like the Movement of other players, Other players Skill Animations and many more Actions will displayed immediatly (through the buffer release). Maybe the Data Centers incomming Hops are overloaded and can not answer to any client side request (including TCP request).
