socket.to().emit() is not excluding the sender

[Zeilar]

For some reason when I tell a socket to send like socket.to(roomId).emit(event, message) the sender, and thus the whole room, is getting this message. The expected behavior is that this socket should be excluded in the receiving room.

socket.broadcast.to doesn't make a difference.

Figured it out, problem was that I made every socket leave their default private room, like socket.leave(socket.id), which apparently caused bugs like this to occur.
