My minecraft world which will soon become a server has a area that allows players to tour a remake of a youtubers world, though for some reason players can break paintings while in adventure mode, I have tried making them visitor but they can still break them, Ita annoying as often times i forget what type of painting was in that area and cannot replace it, I have tried fixing it myelf but to no avail, it has been possible since adventure mode was a thing and i hope to see it fixed someday
