Hello, I've run into a bit of a problem. I'm running TANE SP1 HF4, steam build 84473. While working on my mountain route, I can't adjust any vertices above 3000 meters, either by applying a vertex height or using the height adjust tool. As soon as I click on it, the vertex immediately drops to 3000 meters. Anyone else have this issue, or am I missing something here? Thanks for any help.
