I went onto some random server and I didn't spawn with my default weapons. All I had was a physics gun. Which was what I was spawned with when I started a singleplayer game after this. I had nothing else. How can I get the other guns back?
Start a game, hold down Q, and click the tab that says "Utilities", A.K.A the tab to the right of the tab that says "Tools". Then click the thing under "ADMIN" that says "Settings". When you click on it, there will be some boxes with checkmarkss in a couple of the boxes. Look for the box that says "Enable weapons". Click on it, and when you're done, your guns still won't be there. So exit the game and return to it again. Your guns should be back. If it happens on another server, just repeat.
