Broken since 9.1 if player has continued in the campaign.
Impossible to find other players that JUST HAPPEN to be on that part of the quest chain where Eye of Jailer still exists… No party sync possible.
Party sync should not be necessary in first place.
That is quite frankly unacceptable when you already have a character who was half-way through the achievement then unknowingly had it made unachievable through the carelessness of the game developers.
It is quite obvious that ‘they’ simply ignored the consequences of their actions, not giving any thought to the players.
