I was losing the battle, so I clicked Admit Defeat.
Right after I did that, the game figured out I was beat and put the ‘lose’ window up, I had the chance to go back to deployment, so I clicked that. Deployment appeared.
The Admit Defeat ‘are you sure’ popup was still there, I said yes, I was beaten.
The statistics screen came up and wouldn’t close, and there’s no way to close it. The only button is Main Menu, I clicked it, I got the splash screen with statistics screen overlayed.
