Is there any restriction on how deep in water strongwall will work on a tile? I have a tile that i was going to tunnel into to force the tile i want my boat entrance on to be deeper. The tile is too deep to tunnel if you are standing in front of it but i could open it up from the side okay. I just do not want to get stuck without being able to strongwall it shut once i do open it up. I think it will be about 46 below water once the tile opens up. NVM: It will not let me tunnel from the side either like i thought it would so i can't open it up anyway.
