"Sending player information to server"

[FaZe Booce 0]

Whenever a player joins the server they are added to the database normally. But whenever a variable is changed (say they take out money out of a ATM in-game and re-join, they will get a "Sending player information to server" text and it will stay like that.), they cannot re-join the server with the modified information. But if they leave their money at the starting amount and don't change anything and re-join, they are allowed back into the game. So the issue is if someone takes out money or if I edit their player in the MySQL database, they get this error. Does anyone know the source of this issue?
