Platform Ideas

I am enjoying using the platforms but there is a learning curve. If you build the room first and then add a platform the walls come down. If you start with a platform and then build a room around if form some bizarre reason when I enclose the room the platform jumps up 4 levels in the air and deletes your bathtub, and I have to bring it all back down again. putting a platform next to another platform automatically connects it if they are the same height with no option to un-connect so I have to build it off to the side and move it. I think I am getting the hang of it and I am sure it has to do with the way the walls and platforms interact but I wish it a little more intuitive.
