Dragon clan conquest market merchants bugged

Playing Conquest with the Dragon clan on hard mode,
Ubuntu 24.04.5 LTS, Proton experimental DirectX
Seed: 616111592 Medium size
Reproducable by building a market and putting 2 or 3 merchants inside. Just in conquest, haven´t noticed it in other games.
The 2nd and 3rd merchant on upgrading the market won´t do anything and will just sit idle outside of the market, leaving me with 1 merchant, unupgraded, or 2 merchants upgraded.
This is the 3rd game in a row in conquest that i've noticed this, I don´t have info on the other maps since I didn´t think much of it at the time, I've pasted the game info onto the picture while making a screenshot selecting the market.
This is a link to my autosave, for some reason it won´t show my own save in the save map, so I've put the conquest autosave in there, hope it's the right one.
