Previously explored tiles being regenerated with palisade walls

[venum4k]

Describe the bug

Mapgen is creating palisade walls and "Null" on some tiles that have already been generated.

Attach save file

Cocodrie-trimmed.tar.gz

Steps to reproduce

I'm not sure how consistently reproducable it is beyond exploring to find more tiles where this has happened. If I find any more tiles on my save I'll mark them down in here.

Expected behavior

I expected that the generated tiles wouldn't change when I return to them.

Additional context

Here's a few more images from the lumber mill, this was a conveyor belt, concrete floor and chainlink fences before it became shingle roof, "null" and palisades.

That looks like the error report I got when it first happened too.
