when i'm on my server i try to use the vanilla commands on the server as op. it seems i can't quite use them properly. this was confirmed when i was using SpigotEssentials and disabled the SpigotEssentials tp command and tried to make it default to the vanilla command, this still didn't do this as it didn't execute the command. I feel as if this is a spigot issue as it shouldn't have anything to do with SpigotEssentials at all. I do apologise if this is wrong.
