Wasn't this always the case tho? Irrc, class loadouts NEVER saved properly. Or was this fixed at some point only to get broken again?
At any rate, I need to comment how incredibly amusing it is to see something so basic as saving class loadouts not working. It's even more amusing when you realize that all the work that went into creating the Armory menu is rendered completely useless by this trivial bug. Classic Bannerlord.
