Work perfectly with 0.85

Does this happen all the time? How about for arenas without numbers in the name (I assume "15h" is the arena name)?

@skaterzero807: Go

It happenned all the time (other arena are named 16h, 17h, 18h, and so on) Sorry but i can't test it furthermore right now. For now i'm using 0.85 with cb1.4.5-R0.1 and it works perfectly.

Same issue with server version 1.4.7 Beta. No numbers in my arena name either
