I was with a raid group and we ran the challenge and defeated Golgoroth but only three of us got loot. I know that running and completing the challenge, guarantees 310 loot. Three of us received nothing but a critical error message once the boss was down. I checked with the postmaster and didn't have any 310 stuff there waiting for me and neither did the other two. Is there a way that we could get the loot or would we have to run it again and complete the challenge? I know it gave me credit for the kill because I have completion in my King's Fall quest. Anyone else had issues like this?
