Now I dunno how you're going to do this without Nickserv, Peppy...
But if you're connected to IRC with Osu! and get disconnected, your ghost is obviously stuck there for ~600 seconds and there's no way to kill it. This generates an 'unable to connect' error.
If you connect to chat with Osu! and the name is already in use, the old client should be kicked off the network. Easily done with a ghost command sent to nickserv, but you obviously don't have that.
