Removing brick tiles creates water in specific place.

Well weird bug.
Trying to remove some brick tiles to recover some stone blocks suddenly the land was remover and water was created below.
However only in a specific part the water was created and even weird thing was that it was bigger but when i removed the brick tiles on the side the mini pool shrunk.
The placed items still work the gate open and closes properly and the walls that were on land are still there.
The map was created using the in game map creator.
Have Electric Furnaces + 90° inserters + a few modified items (steel electric furnaces and M4A1).
i still have the save prior to the bug in case is needed and can send you the modfiles or remove the modded items in case you need to play the save game.
Thanks for this excellent game and keep the good work.
