I'm currently using Bpermissions. After a player completes his requirements he ranks up and everything. But as soon as he disconnects and joins he is his old rank again or after a server reload. A few minutes later he auto ranks up again to the rank he was before disconnecting. I can disable the spamming in chat as the whole server gets pretty much a rank up or a few. But why aren't player rank/group saved?

So they either have to manually check or wait for the timer to come around.
