Here is what I don't understand. I'm starting with the standard forest with a hills addon, and everything works. I can raise and lower the ground and add hills with no problem at all. So next I add grass that is used in another tileset to the standard forest with the hills addon. Now I can't raise the ground at all and if the area already has raise ground then when trying to open it up in the toolset it crashes.
So everything worked then added walkable grass from another toolset and BAM screws everything up. I'm a newb at all this so I don't understand why or how to fix it. I know some of you may be like that is so easy whats your problem.
Sorry but I work on houses for a living not computers '>
