Been progressing through Nightmare for a few days. I was in Act 3 when I switched back to normal to do the cow level for a bit, and now I can no longer select Nightmare difficulty or join/create a lobby in Nightmare. I don’t know what to do. I killed Baal again, even though I’ve got the Slayer title logged; relogged into Battle.net, switched sever regions unistalled/reinstalled seems like this character is soft-locked, non-laddered
