Strange glitch

Hi, im new to Facepunch and have been viewing several threads about Gmod and other things but i couldnt find a thread on this. Yesterday while playing single player gmod on “Badlands.” I switched to another tf2 map and i noticed i had no weapons. I only had the tool gun, camera, and phys gun. i switched maps but still no guns. I waited awhile then tried again and it wont work. Anyone know how to fix this? If someone has already posted about this i apoligize.

type sbox_weapons 1 into console

Singleplayer Menu
