Hello, Looking for help here.. I have a tunnel entrance.. And it is too deep according to the tiles adjacent (tiles right and left). I cant cement the entrance corners because "The ceiling is too close." i can't open a next tunnel above to make a 2x tall entrance because it's impossible "Another tunnel is too close. It would collapse." Is there any way to fix the slope? Without collapsing the tunnel. Is there a way to make 2 tunnel entrances next to each other? Thank you.
