1.35.0.19887 Terrain editor plateau height tool broken

Hi, one of the newer patches has broken the terrain editor’s plateau tool in a way that makes it create 90 degree terrain slopes every time it’s used.

Steps to reproduce:

  1. Create new map
  2. Raise terrain
  3. Close editor
  4. Reopen editor
  5. Reopen map
  6. Use plateau tool on the raised terrain

This behavior is normally only available with the help of local files (a modified ui/miscdata.txt), and some terrainers do intentionally do this to their maps, but this should not by any means be default behavior.

Edit: evidently this has been around since 1.32
