v.175 – Heroes of Maple: Blaster Patch Notes

The selectable cube coupon was exploitable last time around - caused a ton of people to get accounts chain-perma banned because nexon is dead set on believing it was a dupe. This makes me think they have no idea of the root cause, and it probably won't be fixed for this.

I suggest staying away from cubed items for a few days - don't help any friends/randoms transfer, since just passing through your character is grounds for perma ban with no appeal.
