I made a map, not done yet, not finalised, but got the basics done like the design and some textures. (designed to be simple map for buddies). Basically i was testing it out with scout, running around. but when i ran out of the spawn, I just saw a gaping huge hole in the floor. I ran over and was blocked by some invisible thingy. And it was sticky -.- i had to fan myself away from it. Also, this is plain curiosity but, while i was still making the map earlier on, i tried it out and kept falling through the floor. The respawn trigger thing was above ground, player entity above ground as well. I checked back on hammer and it showed the ground there. I had to delete it and put a new one in o.o Can anyone help me with the invisible wall problem and the fail glitch floor question?
