you lack support, no matter what color it is when you place it, its not enough from the sound of it This interface could be better, for sure.

Well, I'm just going to download a mod to disable the support system till I hear it gets revisited in an update. Hopefully the support system is one of the things they'll work on in the next major update that's coming. Honestly, I like when a game encourages you to support your buildings, as it ends up with you making more realistic and interesting structures, but there's a fine line between realistic and frustrating.
