This is a pretty big bug, and I've been investigating it for a week now with no success.

Below is the issue in question.

Painting, height changes, and even adding/removing textures aren't usable while the broken terrain is selected.

Creating a new terrain works fine. Editing the new terrain works fine. Saving the terrain causes the same crash, whether the broken terrain has any edits or not.

Larian, Please advise us on how you worked around this bug during development. I know you don't have time to fix editor bugs right now. Just give us the knowledge we need to work around it.

UPDATE: Norbyte in the IRC is going to great lengths to diagnose this issue. Thanks Norbyte!

UPDATE2: Looks like something was added in a recent-ish update that broke the terrain optimization. It wasn't in the June version.
