[Help] Map Textures Keep Changing

[chuckduck]

When i paint my map its all fine and the textures come up correctly. But if i reload the map after shutting down the editor. Or if i change a texture setting in the editor bar. The layer 1 of my pallet, changes from stone tiles to this:
The texture changes from STONE TILES to CLIFF

It may be because is used T-paint and my original t-paint texture way rock. But how to i get it to stay as the texture on my layer.

Another Problem im having is that these pink poloygons keep flashing up in the sky when i move the editor camera.

This picture only shows one but normally there are more of these little pink devils.

Thanks for helping meh sort this out.

For the Sky, Change the skybox and reset it.

For the textures make sure its at same elevation
