A hatch would not burrow into ground blocks that had been reserved by a tile build outline after day had returned. The tile outline had been placed the prior day while the hatch was still buried. In the attached picture the hatch is buried in the only ground block that is not reserved but it would not burrow until that ground block had its tile blueprint canceled.
Created a new world with the just released thermal update preview build. (Steam user) Placed tile blueprints on the ground during the day while the hatch was burrowed. Night came and the hatch surfaced but when day arrived the hatch would not burrow again until one of the tile blueprints was canceled.
