Just for the record, what difficulty rank purge is this?

There are some purge waves that are all nude. I think they’re referred to as “conscripts”, but I could be misremembering. Basically they’re prisoners being forced to act as shock troops and cannon fodder. So it does kind of make sense that the people using them might not bother with giving them more than an old rusty sword to fight with.

Other than that, you mentioned you do have mods, and even though they supposedly don’t mess with player models, any new update can bring with it weird unforeseen interactions between the mod and the game.
