Alright, there's yet another map I've been designing that has terrain forming problems. It's happening on most maps I've tried munging as of recent. Here's what's wrong...
This is the terrain in ZE, all formed and ready to go (notice the bridge there, that's important):



And this is what it came out to be ingame:



That's by one of the turrets from the first shot. Notice how the river isn't there once munged.

And here's the bridge:



As you can see here, only part of it munged. The upward terrain seems to have survived, but the terrain that went lower, such as the river, disappeared, and the river and the bridge were stuck underground with it. I've had several cases on different maps where the terrain disappears entirely, leaving various objects hanging in the air.

So, exactly what is happening here?

What is your terrain size? It must be a dimension of 2 (Like 128x128 or 256x256), or you'll get problems like this.

384, I think. I thought that fit, though.

Nope. It has to be a dimension of two.

Argh. Now I have to redo everything...oh well, thanks.
