I have the Problem i sold 1x20, 1x50, and 1x30 rc via Player Trade for 6k, but they are still in my inventory. I could not ask the player if the have got their rc, i hope i didnt scam them.
I tried it again with a test rc with a player, the player got the rc, the rc count in my inventory stayed the same.
If the player trades me an Rc, it disappears for him, but the number of Rc does not change for me.
Further testing with a Choise Scarf and Berries, showed it also affects other items.
It seems to be fixed.
