I was on my Minehut server trying out some new commands when suddenly... nothing heppened! The invisible item frame command won't work :/ Anyone got an idea of when they will update their commands? If not, is there a plugin for invisible item frames or something of the sorts? I just find it really annoying having to type this over and over again... /summon item_frame ~ ~ ~ {Invisible:1,Fixed:1,Facing:1,Item:{id:"iron_sword",Count:1}} ↑ Name of item and /data merge entity @e[type=item_frame,sort=nearest,limit=1] {ItemRotation:1} ↑ Amount of times you want to rotate the item
