[Fixed - persists in 3.87] Null-issue while trading (3.87 stable)

[Kreivos]

I'm in a village where I did a minor quest worth 5 squirrel hides. Now I'm trying to trade things (fish and yarn) worth more than that and when I return items in the trade, the threshold for 5 squirrel hides worth won't activate. When I'm past that and asking what items would be preferred in the trade, the answer is null.

Do you happen to have savefile available?
Would help a lot to find the spot to fix.

Yes, I'll send it via email

Nevermind, too a big of a file. It's here: https://drive.google.com/drive/folders/1C4TIl1-3u_chLHJwm2kqO5sjQZVCvJtt?usp=sharing

It seems the reward compensation calculations weren't updated at all when unpaid items were returned, but only if new items were offered.
This was a rather tricky thing, but got it fixed now.
