If empty teams list shows label "add at least 2 teams to play", it would be easy to understand how to run a local multiplayer game.

r98e4a60da2ca adds a label, but has issues: 1) actually need two clans, not just two teams 2) if you add two teams, then press 'Back' button and return again, you won't see the notice

Also as ink reports "If a different player adds 2 teams, the message doesn't disappear from your client right away like it does if you add 2 teams yourself."
