I am working on a map and the other day it wouldn't update. I checked for bugs and found that my light_environment had a key value it wasn't supposed to have so I remade it. I then tried to compile the map but now it's just a big glitchy mess. First of all, it did not update what I had made, but it did, I guess, update. Nothing new was there but I could see through walls and props and they would only appear if I looked at them a certain way. I'm pretty sure it's not a leak because it didn't look like one, but I'm not that experienced in mapping so I don't know. I pressed alt+p and now it's showing me a trigger_hurt in my map has a key value it shouldn't. Clicking fix does not fix the error. I'm not sure whats going on, can someone help?
