For some reason, I can't load terrain height maps anymore. I have already made a map, but It won't load my new terrain map. It will load my previous one fine, but if I try to load up my new one in game it freezes and a box pops up sayign game has stopped working, and I have to exit it. My map size is 513 x 513, same as the other one.
And looks like this,
(Ignore the white bit around the side, that isn't there on the map.
Is there anything I can do to stop it? I can't make any more maps because of it.
edit- Its that one map, I have quickly made another and thta too works fine, can you suggest what has gone wrong?
