Just wondering, because I hate having to reinstall old maps due to me accidentally opening them into Roblox Studio instead of Novetus.

Convert the way Finobe Does. Get a 2013L Studio and a Converting Save/Load.txt files to restore the brick colors. You can find a text tutorial on that here, or you can use a youtube video. It's also in the Novetus Discord Pings (modding channel i think) https://wiki.finobe.com/index.php?title=Converting_Maps
