Hey guys, I've joined the forum to ask you guys for some help, since you all seem to know a lot about hammer and such. I'm working on my first map for TF2, titled cp_express. It is going to feature large gravelpit-style capture points, with a twist: there is a train that goes through BLU's spawn periodically, which can be jumped on and ridden to point A. RED has a train that goes to C. Neither have trains to B, and it will be the shortest distance away. (I <3 trains) However, I have encountered a serious problem. Whenever I run my map, none of the changes I had just made are actually... changing. That is to say, it is the same as it was 3 tests ago, even though I have changed the architecture signifigantly. What's wrong? This happened before with another map I tried to make, but I eventually gave up. Please please PLEASE tell me you guys know what's wrong!
