Is there any way around this?
If you could get Mission Editor working, you could try selecting the bricks and moving them, but back in v8, i tried moving bricks with Mission Editor, the bricks moved, the collision didn't, so it was messed up, so that don't work, if you have the Duplicator Add-On and your build is all one thing, you could select any of the bottom pieces (Or just the very bottom part you started with, like a plate or something), and move it up to the Bedroom floor and then place the duplication there, otherwise, there is no way around it
