hammer slider gone, map turned green

Describe the Bug
I was creating a dungeon in build mode, then the hammer icon slider disappeared and I ended up below water level. I tried to find the build level but can’t find it. I then tried re-launching the build and now can’t seem to do anything

To Reproduce
No idea, I don’t know what I did wrong
