The build/version number is a good idea.
Ok this sounds like you caught a weird edge case I need to fix. After deleting the loadout did you create another name for a new loadout in that same window, and then click add, or did you delete and then click save? It sounds like you managed to create an unconfigured loadout with no company selected, because even if you had nothing the game should have loaded the tutorial loadout in skirmish.
