The server list for 'friends servers' does not show external servers from remote hosts:
e.g.:
add beta.inpvp.net (occasionally going up and down whilst we debug)
add sg.lbsg.net
Former uses MiNET, latter uses PocketMine-MP.
Both presumably have correct packets being sent.
PocketMine and MiNET both show in player list when running on a local network, remote they do not. Please, please, please fix. It's causing some bad harm to player counts on server networks.
Please do not mark unreleased versions as affected.
You don't have access to them yet.
