A bug was discovered after the latest reset that resulted in all players earning more BXP than they were supposed to. Extra BXP was being awarded on many activities in the game (not just login). Some players exploited this bug and gained excessive BXP (shame, shame)! Most players probably did not realize they were getting extra BXP.
The bug has been fixed and many players have now had their BXP reduced.
Sorry for the inconvenience and thanks to the players who helped us identify the problem!
