I just started getting this error after last wipe. . .I'm a server owner and I sometimes use /tp <player name> <server owner name>    but recently it say's "Player Not Found" on every player I try to use this on. . .please advise.  Thank you.

By the way, all other functions work. . .for example, if I try to /tp <player name> (to the same player I attempted to /tp to my location, it works by TP'ing me to them. . .but the reverse say's 'Player not found'

alright thanks. I'll rewrite it since it's dated and overly complicated
