If you're using the most recent version of SPT, that could be your problem as modding was changed with a recent update.
You used to be able to get away with having SOME "outdated" mods, but now it's "Current version or expect bugs. Possibly really bad ones that corrupt profiles." Check out the big yellow box of text at the top of the mods page.
Thanks for the clarification! Luckily its just the scav case so ill do w/o it for now until updates come, or just go back a version
