Gmod 13 server addons not showing up

Most of my addons after getting my host to reinstall everything with steampipe, DO NOT LOAD!

eq. Madcows Weapons from gmod.org

These addons are located in the old file location of [username]/garrysmod, with the update to 165 and to SteamPipe, Garry’s Mod’s new file location is in common/GarrysMod. You should move your addons from the old file location to the new one and delete the entire garrysmod folder from your [username] folder. Make sure you verify your game cache afterwards to fix any broken dependencies.
