Okay, soooo..... there's a few funky things going on:
It looks like some skins' pathings are now misformatted, given the error messages I'm seeing. Basically, the game is being told to look in a certain location for something, but can't find what it's being told to look for. (This is just a guess, I have no idea how to mod this game.) Some skins do work (see the Marina example) but some skins got borked (see purple untextured Sasha hair).
The good news is that the skins for characters are not completely gone, you just need to use the radial menu for now. Most of the skins I checked seemed to still work, but I didn't check all of them. There's also some funky menu brokenness going on, but I didn't look to see who was affected by it beyond Aurora.
I'll lurk around the official Discord and see if any of these errors get reported or any hotfixes get pushed. Until then, I'm going to keep my mod archive unchanged, since I'm confident these errors will be resolved before too long since they impact a bunch of mods (and most skins are still useable).
Also, Aurora got voicelines????? *looks at cock* It's so over for you buddy...
