Clear Sky - items sold to trader disappear

[argosurvivors]

Describe the bug
At the Garbage at flea market there is a trader Toshka Moped Loner.
If you sell or donate any item to him it will disappear from his loot.
I suppose there is a problem in a script considering in which inventory boxes will new item be placed.

To Reproduce
Steps to reproduce the behavior:

1. Go to Garbage at flea market to a trader Toshka Moped Loner
2. Go to trade and sell him or donate any item
3. Go to trade again and you will see that he does not have it in his loot

Expected behavior
A trader should keep items in his loot so you can buy back if needed.
Error is attached only to this trader in game.

Is this behaviour the same as in vanilla Clear Sky or it's the bug of OpenXRay?

[argosurvivors]

As I remember this behaviour was in vanilla Clear Sky too, here is my saved game at that place.

I noticed if you sell him ammo, grenades or medkit it will be saved in his inventory. If you sell him weapons they will dissappear.
