Lost Sun Clan Relic in Cruel

Bug Ref: 614,568,624

Somehow I have managed to delete the sun clan relic in cruel difficulty. I was having trouble inserting the sun clan relic into the holder. I remembered I must have done it in normal act 2 so I went back and then realised I needed to hold Alt down to keep the relic holder open but too late, it had accepted the relic from cruel difficulty and now the sun clan relic wont drop from act 2 anymore. Help fix please, I'm missing the reward.
