Ok. Fix incoming today for everything listed above, except for the Lunar Ball improvements.
I *STRONGLY CAUTION against using the wall editor in the last build. It can result in walls that are placed facing the wrong way, which will confuse some of the games and cause spawns outside the map. Update today will fix the issue, and it _should_ be very possible to redesign and replace walls however you want, without needing a hard reset / loss of high scores / loss of custom apartment save setup.
