Ladders only placeable interior walls

Garry,

Please make ladders only placeable on interior walls instead of blocking it completely, I think this is the most balanced option.

Nah, it would be too easy for raiders to place them once they have broken into your base.
Being able to place them on rocks even with building blocked would help get rid of rock bases and bring more balance to the game though.
