CANT PLACE THAT HERE

[GrandMast]

Villaged called GM2 in France

Today I started to rebuild my castle yesterday as it wasn't a good build so I started to "delete" walls and replacing them with a better construction. Yesterday all worked fine.
This morning all worked fine.
This afternoon when ever I try to place any wall or building I get an error.
I have made a huge hole in my outer wall and open for attack. I can't even replace the part of the wall that is missing.
Can you help

I can't even move my tunnel on that one village, the other villages work just fine
