I have done 3 hard raid on the last 2 days after the patch. Defeated Atheon and it does gave me loots. However I played again normal mode last night defeated Atheon and it gave me no loot. Did you only receive loot once by defeating Atheon on cumulatively on hard after the patch. Because as I remembered before the patch defeating Atheon on normal and hard will give different loots. P/s: I usually completed normal before initiate hard mode.
