I compiled my map last night because I wanted to see if I made any mistakes yet, and it ran fine. I realized that the volcano's slope was too hard to walk up without problems, so I added a flight of stairs (They are props, by the way) going up the volcano in front of either spawn. I also added a Raygun at the top, along with a platform and a few other tid-bits. Now, when I try to compile my map, it runs the old version. Why is it doing this and how do I fix it?
