It seems there's still a slight issue with saving (or rather loading/applying) of the laser projector code. Looks like the Load Save feature seems to get the code confused for the first few times you attempt to load the save. If you load the save enough, eventually it will be correct.
I noticed this when I joined back to my Condo from the Plaza and one of my Laser Projectors was using the wrong code. I started recording Video #1 after noticing this. #2 was me replicating it.
