When saving "terrain defaults" without any nodes in the node graph results in endless node compilations (maybe just progress bar freeze), and a flat projection of the last compiled terrain, on a new one.
Steps to reproduce
- Open Gaea
- Delete all nodes
- Go to the menu on the top left corner, then >Workspace>Set Terrain Defaults>Custom Default
- After saving, create a new terrain
Now you should have something similar to the image below
