I'm not quite sure what you mean (I'm not the most tech savvy), but I've left everything the same, I have not touched my DCCache folder, and the Sunlit Tides.world file is still in the Installed Worlds file. It did not work, and probably had no impact anyway, but I had put somebody copy of their .world file in the installed worlds folder, thinking it may be corrupt. Nothing happened of it, though.
I'd also like to say that the Sunlit Tides objects (the fruit arrangement, pool light, etc) have no names or descriptions. It's really only a cosmetic issue, seeing as how they're still usable.
Massage Table & Sauna do work, however.
