Recently my hammer compiler has been acting goofy lately. I'm trying to compile this map I make, but it keeps getting stuck on portal flow. It does get stuck. I went to sleep and came back in the morning and it didn't budge. I tried making just a block with a spawn on it and that compiled fine, so its not totally broken. I then tried re-compiling my map with no skybox or lighting, and that worked. So now my thoughts are stuck on the lighting is the issue. True or not, i sent it to my friend to see if he can compile it, and it worked for him. Lighting and all. Now I'm totally confused. Is my Hammer broken? Can anyone post thoughts on how to fix this please?
