Have no idea what's happening. I've disabled every workshop addon, and the only addons that work for me is the ones I converted from the .gma file to a folder based addon (like the GMod 12 Addons but for GMod 13). If it's something like a prop it will show up but it won't spawn, if it's like a vehicle (TDM Cars or SGM Cars) they don't spawn but appear in the addons folder. I have no idea what's happening but I've only experienced this bug this week!

Any help will be appreciated. Thank you
