At spawn someone did mess, but how? Or did the administrator or a player, but I think I know which way. Why not spawn has established a lock on thaumcraft wand? As for the plots of other players wand is removed from the strap to the equipment? Administrators can not be any question blocks Provide protection focus "Warding"? Then the players could not move the blocks or to interfere, or to protect the spawn so that you could not come at him with a wand.
There was an issue which prevented the protection plugin to load correctly. I already fixed this yesterday. The spawn is now back to it's normal state.
