Another useless weird fact : I’v build stuff inside my shelter, and i ended by building wall inside it.
here is the middle of the shelter : (Actually, there is more wall around but i don’t think it matter)
S = stairs
W= walls
. = nothing
......
.WWWW.
.WSSW.
.WSSW.
......The two square of stairs on the top side are “outside” the building : I can colect rain, and get damage from acid.
Not a big deal but anyway.
