I don't add a lot of mods too often, and the only gear mod I've really added had been the black gears that I just added, but this had been happening before that.
I actually have been having two problems, one is extremely confusing to me as I've got zero clue on how it happened, but my Schmidth & Bender PM II 3-12x50 34mm Riflescope is turned into a doge box.
My other more persistent issue had been with playing as the player scav. Whenever spawned in, the arms model never is the actually outfit of the Scav I'm playing as, and whenever I go into the 'Overall' menu while in a raid as a player Scav it goes into an infinite loading loop that never loads the model and freezes the menus so it stops me from clicking back to my gear or to the health. Only when I go to another container and open it that it forces me into gear again, and once I'm done with the raid and hop back on PMC my menu's are still frozen and will not let me switch, I have to restart the game to fix it.
