So when i do carpets set default false or just carpets set false when i shift the carpets dont dissapear and i dont know what else i have to do.

Going to close it as this isn't really a Carpet issue (unless I'm missing something), though if you still need help feel free to comment again or join the discord.

Did you for some reason install the carpets script (a part from carpet)? Remove it from your scripts folder, it shouldn't be there. You should be able delete it by running /script remove carpets, or by going to your world's scripts folder and removing carpets.sc.

Also, do you know how it got there? It's not a thing by default, and it has happened an absurd amount of times that I think we're doing something wrong on our side.
