the terrain in the last two maps ive started doesnt show up in the the right place.
for example, i made a canyon and placed some ruins and cps nad made hilles on the
canyon wall but i munged and the terrains way off in the distance. and since
i made hilles with cps on them units just fall out of the sky wheer the hills
should be. ???

A) Your map isn't a size that's a power of 2 (256^2, 512^2, etc.)
B) You resized your map after you'd already added objects

hmm, i usually make the terrain bigger before anything but ill try again.

Remember, it MUST be a power of two or you'll have major problems like this. So 2x2, 4x4, 8x8, 16x16, 32x32, 64x64, 128x128, 256x256, 512x512, etc. I wouldn't make it smaller than 64x64, and most definitely no bigger than 512x512. That doesn't sound huge, but it's massive.
