Hello!
Similar problem. We play with my friend in multiplayer.
I have items in my inventory, but I can't transfer anything. My friend also doesn't see my inventory at all.
After that, my friend said that he could not save our progress, even though we had just slaughtered all the goblins at the party(and it was difficult, I'll tell you).
The game wrote "a new save cannot be created during the dialog.". When I already left the game, a friend said that I hung up on the dialogue with SHADOWHEART.
I think I'll have to slaughter the poor goblins again tomorrow
