Dinkleberg's GMod

Screenshots aren't working, but I'm having trouble buying some of the skins in the F4 weapon skin store.

Specifically, I am not able to buy any skins for the following weapons:

• Auto Shotgun (not sure why this is an option)
  
• H.U.G.E.-249
  
• Rifle
  

When buying skins for these weapons, you get the "Weapon Purchased" noise and message, and the skin appears green as purchased. When closing/reopening the store, the weapon skin appears again as if it were not purchased.

The weapon skins do not appear in the inventory, and I do not lose any money for purchasing these.

Update, the glitched weapon list has spread to the following:
- Auto Shotgun
- Crowbar (weapon_zm_improvised)
- Deagle
- H.U.G.E-249
- MAC10
- Magneto-stick
- Pistol
- Rifle

This did not resolve on server reset. I think i've already purchased the skins for these guns, but it is simply not allowing me to equip them. No idea why
