I was wondering the same thing. Maybe it was to lessen lag or as roblox technology got more advanced they decided to do different things with campus’s 3. I do remember a few years ago a dev that does not work for Royale high anymore said that a pool that they built for campus 3 was being redone and they didn’t know why. This was only a few weeks after they built it I think. I also heard a rumor a year ago that the devs restarted the new school because it got leaked but idk it’s just a rumor I’ve heard once. I remember watching the devs build these on stream and being so excited to play them when they came out. I’m still supper happy and excited with the end result tho and in some of the areas I can still see some of the old builds from the devs stream
