I was wondering if this could be made at all possible. I've been looking around in the inis, but I can't find anything.

Right now, when you join a server, you can fly to someone, and join their group. Me and friends do this a lot. But sometimes I lag and get disconnected because my internet is unstable sometimes, so when I reconnect, all my friends have moved on, I'm no longer in the group, and I must catch up to them to get into it.

Is there a way that you could add the Group Number to the Save File?
