[0.12.2] Terrain bug during path deconstruction

[Bodzio]

After updating to latest patch i observed strange terrain behaviour when deconstructing paths.
After deconstructing near-water stone path terrain extends into the lake (water tiles are replaced with terrain tiles). Also deconstructing stone path leaves barren terrain instead of terrain that was underneath before laying down path.
These two screens are visualising problem (wath the right hand side of the terrain shape):

EDIT:

Also some paths near the shore cannot be picked up with bigger brush size, but when decreasing brush size they are pickable (despite being shown in red colour) but picking them up "extend" the terrain as described above.

Hello, these are the results of the changes we made for 0.12.2

From 0.12.2 Up, the tile under the tile is saved in the savegame, so when it is mined it could be put back. (It used the map generator before, but it wasn't so predictable and also it didn't work in edited maps).

However in maps from 0.12.1 and 0.12.0, the data isn't there, so it was just set to dirt.

The distance from water has been also increased in the 0.12.2.

Wow! That was a really quick reply! Thanks for clarification. I thought it might be update specific issue.
