ok so when people rankup on my server they get it and it works perfectly fine but if I close the server and open it again and when they come in they have the default rank . the only way they will have their rank they payed for is if I edit it in the users config but I hate doing it for every user. so bascally im saying it doesn't save the group/rank in the users config
