Unremovable ghost cliffs appearing on flat ground...

This is not funny. When I try to use the Cliff: Same Level on this particular section of flat ground, I get a one-by-four cliff there. Before you say "Then don't use Cliff: Same Level", the thing is that my map is star shaped and supposed to be symmetrical, and when I Copy/Paste the part I made to another corner, it also shows up and I can't get it to go away.

I can't lower it with Same Level or Decrease One Level, and when I try to use Deep Water to get it to go away, there are now unremovable cliffs around the area where the water was. $*µ%£@&!

Having to recreate everything three more times is a sucky way to pass a rainy Monday, especially when you're not even sure if the map is corrupt or what.

Any idea of what's happening? It is on a piece of flat ground next to a very steep hill, if that matters, because the map consists of narrow paths through lava [which is accessible, but causes damage when you walk over it]. But those "pieces of flat ground next to steep hills" are all over the map and I don't have any problems with them elsewhere.

I'm not really sure what your asking, but perhaps if you removed your map file from your war3 directory then unistalled then reinstalled it might fix some stuff. Do you use 3rd party programs or anything?

Dont use copy paste and if u mess up press Ctrl+Z:D
