Hey, thanks again for the report. I'm pretty certain the problem was created when I renamed the ore mine in the system. I'm looking into changing this so it's not so brittle in the future (or maybe just prevent myself from changing any of the names), but for now would you mind just deleting your current loadout and making a new one? The game will automatically pull the new ore mine into the list of buildings your game can build. 

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.
