Are you using terrain holes, by chance? If so, you might be running into this issue: Unity Issue Tracker - Terrain object with holes doesn't get a Lightmap generated when the object isn't a quadrangle

If you’d happen to run into a different issue, please report a bug and we’ll take a look.

Ahh this looks to be it!

@kristijonas_unity I also ran into this, reported as IN-31231. In my case the hash in the logged error is always 0000…00.
