What happened?

Everything works fine, but when I save a project, it randomly freezes while saving a layer that contains trees. There are a lot of them; the layer is 280 MB. This problem started after updating to 1.30.

Sometimes it saves without any issues. It doesn't matter whether the layer is active or inactive.

For now, I’ve been getting around this by always restoring a backup, but sometimes it freezes and doesn’t save another layer I was just editing.


Do you have any advice on what might fix this freezing issue?



I’m also attaching the logs from Terrain Builder:

Closing connection to buldozer...

This repeats 8,312 times, but the entire sequence I pasted above:
