Wrong character portrait on save

Why do you believe that downgrading is supported? >_>

It's probably not supported but it may be useful to know that something like this could keep happening in case new characters get added

Ok so basically, steam only checks if the files are there and not if they are the right version. I had the outdated version of saveslot_portraits.tex

I don't understand how the game was working properly if other .tex files (like inventoryimages) were not updated though...

But anyway, my guess is the problem was the game assigns a portrait number to each character, and the portraits are in alphabetical order (wathgrithr -> waxwell -> etc), but over the years the .tex file was updated to include newer characters, so my game was trying to assign the current numerical order to the old .tex file, which resulted on the wrong character being displayed on the saveportrait.

Case closed.
