Bannon bug after friend helped him while i was in Oriath, can't progress now..

Hi,

my buddy helped Bannon in act 10 while i was standing in Oriath but the quest still says i gotta find Bannon and save him. I can't progress now even after disbanning the party, logging onto another character and trying to make another instance in another act..

Anyone knows how to fix this issue?


Thanks in advance.

Were you unable to make a new instance of the first area outside of the Act 10 town?
