Whenever I try to play a HL2 map I'm making for a mod, the game messes up. The strange thing is when I did a test map in the same setup while following tutorials , the test map worked fine. Is my map not working because there are "ep2" or "episodic" props in it? Or textures from the episodes? I tried deleting any props that I knew came from "ep2" or "episodic", but the map still didn't work.
