First of all please don't blame me as I am still using Essentials "maintained" by Spigot and not EssentialsX (yet!), but I think this one could be interesting anyways and the behaviour probably did not change here yet.

So. Sometimes I have players that have login problems because they logged of while floating or hanging in the air and after reconnect they get kicked for flying after a couple of seconds. That issue can be fixed by a) telling the player not to fly on logout ^^ and b) by easily sending them to the spawn point by using /spawn [playername].
I wanted to allow my team mates to use the player argument with spawn too, but they do not have bypass permissions for teleports. So if someone executes a spawn command with player argument the player has to wait the warmup (and must not move of course) to get teleported. If you didn't find the paradox yet please let me know.

Anyway, as for me I have bypass permissions for the teleport warmups so I can teleport anyone instantly but other should be able to do also withing having bypass permission for themselves.

Thank you for reading.
