104 Levels EZ
The BAC advancements add alot of advancements to the server.
But when a new player joined, he got many of them at once. SWS didn't like that so he turned them off.
Later people (UnityChats) were disappointed because they liked getting the extra advancements.
So SWS turned the extra advancements back on.
But due to a bug everybody that was on the server at that time got 104 levels!
