It would be nice to have a upgrade to the invite system, mainly making them persistent, let's say

A. You crash joining a invite lobby and now you need to ask for another one

B. You leave a private world to check on someone and then have to request back, but the person you were with is on red orange or asleep

I believe once invited, you should be able to join that instance as long as it's open or you don't get kicked.

Additionaly replies shouldn't just delete the Invite, like if I say I'll be there in a few minutes, I shouldnt have to request a new one.

Finally, a cooldown would be nice to prevent spam (like 1 invite/request every 15 sec)
