i've placed an hopper were there was a chest before, removed whith commands, and their textures gliches.
i' ve destroyed an area with some double chests using the /fill x y z x y z air command, and then i switched the gamemode to survival, i've selected an hopper and then placed it where there was one alf of a double chest, and the thexture of the removed chest appears, but olso the hopper one,
overlying. this thing happened various times, in all the places where the chests were, but the chests textures(all common chests) didn't join together in double chests, and the block acted 100% like a common hopper
