when you go into the final dungeon in Act 6 of the The Sacred Hunt only the leader gets credit for finishing the dungeon. The other player then has to reform the group with themselves as leader and run the dungeon again to gain any credit for advancing in the Campaign, When you finally get into Act 7 the bug vanishes and now you and your companion are in “sync” again for Act 7. Fortunately it is easier to run the dungeon the second time around as you then know how to aviod most of the mobs and go right to the boss room. But…it is seriously bugged nonetheless.
