Alright so, the oddest thing happened: I was working with command blocks, then i logged off, logged back on the next day, got de-oped, then oped again. Then command blocks broke for me and only me: There was no break or place sound for when I broke/placed them My arm didn't move while placing them, they just 'appeared' I could not open the GUI when right clicking them. I could hear the sounds when someone else did it, and they could edit them. ====== Op perms is level 4. command blocks are enabled. online_mode is true. I was oped. I was in creative. Antibuild isn't on here nor is world guard, as far as I know, just essentials and worldedit is on the server. Anyone got any help?
