Ever since I added a server menu system, first released a few month ago, I've gotten complains that when people try to connect it always says: 'Server has shutdown.'
The player who sent this has 150 friends
This did not happen at this frequency until I added a 1 player main menu system.
I believe this has to do with my main menu being a 1 player server and when someone press join, roblox automatically tries to pair him with a server that has a friend in it.
This friend is registered as being in the menu server, altho he has already left and that menu server has shutdown. Nevertheless he is still registered there and therefore the player is sent to an already shutdown server when he tries to join my game.
Don't allow players to follow others into 1 player servers.
Here's some fan-art that people been doing about this issue:
