I am currently looking to create Mann Versus Machine maps for Team Fortress 2. I have already began construction of my first simple map, conforming to the example map provided with Team Fortress 2. So far it works almost perfectly. The robots will spawn in and make their way to the hatch without issues. The main problems start on tank waves. When it is time for a tank to spawn, the server immediately crashes. I have placed a path within the map for the tank to follow, leading from its spawn to the hatch, and the beginning node for the path has the same name as the one specified in the population file. Yet, the tank spawning seems to crash the game. Any advice to solving this problem would be greatly appreciated.
