[0.12.1] Removing stone brick floor creates "bugged" water

[Cerbsen]

In "New Hope" level 1 removing stone brick floor always creates water with strange blue texture.



//edit:
sometimes normal water and strange terrain appears.

Thanks for the report. This was an attempt at fixing something that didn't quite go as well as planned. For now it's changed back to how it was in 0.12.0 until we find a better solution to mining paths.
