Hey so after beating Baal on normal with 3 of my us friends they cannot join me in nightmare and I cannot join them. The game states we must kill Baal (they can both join eachother no probem) just I can’t join them and they can’t join me. We get the above message about killing Baal.
I know it’s some sort of region lock bug because I invited a EU friend who had nightmare and he joined no problem.
Please look into this before ladder reset!
