[A14e] Furniture transforming into other furniture of same quality when sold

[Ark]

1. What the circumstances were.
RimWorld 0.14.1249 rev958 (Alpha 14 e) Linux 64 bit drm free. No mods.

2. What happened.
I was trading with a remarkably well-preserved trader (age 85, no cryptosleep, no age-related illnesses, is this another bug?), and noticed something very strange.
The furniture I sold him turned into other furniture. He turned a boomalope leather armchair (good) into a steel hospital bed (good), and a marble plant pot (normal) into a uranium stool (normal).

It would appear, that any quality x furniture items sold turn into the first quality x furniture that the trader has.

3. What you expected to happen.
Items not to turn into other items, of same quality or otherwise.

4. Steps we can follow to make the bug appear on our machine.
-load the save
-use Emmie to trade with Doc
-sell boomalope leather armchair
-buy plant pot
-sell plant pot
-end up with trader with an extra hospital bed and uranium stool, no armchair or plant pot

OR

-start a new game
-dev up trader beacon, console, furniture to sell, summon traders
-contact a bulk goods trader and observe the same phenomenon
