Hole can't go deeper, hasn't reached the bottom yet

Sadly, this requires a world wipe.

[Cayur]

literally unplayable!! world wipe needed!

Seems a bit silly. Should block on try to place.

It usually does!

It usually does, yes. If it didn't, then that means that it became occupied while you were building.

I started this mine hole before the floating point had been implemented, so that's why I feel there might be a bug here. It just seems rather unlikely to me that someone just happened to place something in the middle of the cavern that would block my mine hole on the 4th level way out in the middle of no where.

Maybe the area got active by someone passing, thus some bats decided to hang around.
Have you tried to try to continue building after giving the server the chance to unload the lower level (despawning the presumed bats)?

I've tried across several hours

I finally made a second mine hole and there is clearly nothing below it. And I still cannot complete the old one.

Will try to look at it, but can be hard to debug.

Honestly, it's probably just an artifact from the shift to floating point whatever-majiggers. I'm pretty doubtful it'll be seen again.

May be related to floating point coordinate change. Won't pursue unless it appears again.
