This actually happens on every game that you’re not able to join, but a friend of yours. This could be fixed by removing the “Join” button when you’re not supposed to join said server.
I think this happens In all, Roblox game servers since, you are trying to join your friend In, the server that Is not joinable for you, for e.g: VIP servers that he owns, because he configured them, like that. Or because your friend Is In someone else’s private (VIP) server. It just shows you that, he/she plays game, because that person Is, your friend.
I am in the process of checking over bug reports and following up on some bugs that haven’t received any activity in a while.
Is this issue still occurring or can you confirm that this bug has been resolved?
I have also noticed that sometimes there are also team create servers that are shown, not just private servers. You can also not join these, but you can shut them down and boot everyone out of the team create (with developer access) if you mistake them for a normal server.
