No weapons in tool menu

After lowering my resolution due to a recent RAM issue, I have found that the old weapons that used to be in the tool menu (SMG, Pulse Riflem etc.) are no longer there. All that is there is my Phys Gun, Tool Gun, and Camera. How may I get my weapons back? (Not that I need them, but whatever…)

I have this same problem here, I can’t spawn with weapons except with the camera, physgun, and the toolgun.

Note: I have changed my resolution from I believe the highest to 800x600, if that has anything to do with it. However, I noticed that I spawned with weapons during one single player game.
