I have the same issue....
Threw eder out so i could lvl aloth who isnt in my party to send him packing on a quest. Got eder back and like 8 magic items were gone from his inventory, including a unique 2h sword.
I didnt notice this till after clearing like 3 lvls of endless paths and i couldnt stand the thought of doing it all over again, i near just quit.
Lost like 80% of my gold in items.
When is this going to be fixed?
Will you be able to make it so i dont have to reload a million saves back? If that even fixes it...
Odd thing is, im pretty sure all but a single item was gone, had a lone blue mace still in my inventory after.
