Update 8/8/2022
Normally I wouldn't come out with an update, this soon after releasing the first Beta, but something really important just came up. You see this house pictured below? That is The Suburban house, and there is an issue with it, if you are playing with the first Beta. ( Orchard Island Beta A )

The stairs don't work. At least not the first set of stairs. In order to fix this problem, just delete them and than press the undo button. That should work. See I had to place a small freeze in-between the first and second floor, otherwise the roof would come below the garage door, and thus the stairs are taller than normal and span two levels. The problem through should be fixed for anyone who is plays with a version of the map after Orchard Island Beta A. Unfortunately, that's the only version out at the moment, so until it comes time release Orchard Island Beta B, if you are playing with Orchard Island, just go to the Suburban House, delete the first flight of stairs and than hit the undo button. Once a future version of the map is released, this should no longer be relevant, but I thought I might as well warn everyone right now
Update 8/25/2022
As of today this is no longer an issue because it's the second beta now, and this problem seems to have been fixed
