Terrain fails

[the_emo_vampire]

I've made a map before and I did everything exactly this time, but my game crashes when I try to import it. I reread all the stuff in the tutorial and I know I did that, and I made several more maps and it still crashes. I will have a meltdown if I can't get my terrain in the map maker.

[.General..]

Though I'm not too sure what's causing this but if you want it to work, I know a solution.
If you've made previous terrain maps that have worked then open one of the old working ones in gimp, then just copy and paste your new terrain mask over the top and save it as a different name. That usually works. If it doesn't then perhaps something is wrong with your map maker.
Hope I helped~
