I've found a bug in the code referencing the new arena command. I'll post exact steps that are needed to reproduce this bug, the undesired outcome, and the possible reason why this is occurring.
Reproduction:
First, start an level 2 Arena with any given amount. Second, have only two account join the arena so the arena will fail to process. Third, Wait some time and start another arena. Fourth, have people join in and make sure the arena starts.
Outcome:
The first arena will fail and tokens will be refunded; however, the second arena will activate correctly, but the amounts and users who enter will be different. The arena will add (or triple) the tokens to the current arena from the failed arena, even the members who joined could "double up" on the entry.
Possible reason:
The failed arena does not have a clear function in the code. It does not say "Arena closed and needs cleaning"; which would mean that the variables being used to store the information is getting added and never cleared. This would account for my observations on this new arena system.
Any credit would be nice for the discovery, and or nicely written bug report.
