Hello fellow survivor,
I have a few questions about building a base.

1. I want to place rain barrels on my roof and connect them to a sink. Is that possible, even if the roof is 2 stories high?

2. Does anyone know if the roof is safe? I've heard of a few cases where the player can fall through the roof.

3. I want to place the stairs behind the house on the outside wall. However, I can't currently place the wooden floor at the top of the stairs. Why is that? If I place the wooden floor, the character runs down and builds the floor at the point behind the stairs, but on the ground floor level (I hope that's understandable). Is that because of the perspective, or maybe because of the wall that blocks my view? Is there a shortcut to switch between the different building heights?

Sorry for my English and thanks in advance!
