We have received several reports from players who are informing us that they have not received their arena points during the last calculation and that arena games for the previous week were not reset. The affected realmpool is Reckoning. We are aware of this issue, which at present is under investigation. We are currently unable to provide an ETA for when this issue is expected to be resolved, however we will keep you updated as more information becomes available.
