I have the same problem - it's across all my recent saves.

It seems like if your main character is possessed by the demon inhabiting the dwarf, it breaks the game and that character doesn't get returned to your party properly (seems like the player is an 'ally' rather than a 'party member', but they are also the player character).

At this point, I cannot talk to my party, have difficulty grouping them, I cannot use magic pockets without crashing to desktop, cannot see spirits any more, quest icons etc are all gone from the minimap, and all NPCs (dead or alive) appear as party members on the mini-map and in when highlighted.

There doesn't seem to be a way around it. I've started looking at editing the save file, but can't see anything amiss just yet; doesn't help that I don't really know what I'm looking for.
