Friends don't show on the friendlist:
This could be lag but it has been happening to everyone, also this bug causes a game crash, thats when you press on Invite button then it opens who is online, but since the friendlist is missed up it says no one is online although there is some who are online but they aren't being shown on the list, then it straight up crashes with the message "Unexpected Error".
If a friend of yours who isn't showing on the list is in your battle he won't show on friend tab either, I was playing with a friend of mine atr139 and look how I was on his tab
Extra: I was unable to send messages too for some reason, not sure if that's connected to this bug but there must be something missed up in the connection.
