Problem/Bug invalid world(when tp still is being excecuted)

since...recent, the issue i get with teleporting to any generated world(via mv) is "invalid world possible worlds are the numbers 0 through 2 you can also type the name of a specific world." But the funny part of it all...it will still even though its a valid world tps me there, and thats not the biggest issue if it was just showing up using "mv tp <worldname> its also showing up using /warp <warp located in that world> This would not show up nicely to users...
