So Maint started at 8pm EDT? dang, I missed stopping my scouts by 20 minutes. OH well, the timing is a little funny (maintenance at end of first day of new research items).. I would have done it for the first 4 hours of the first day myself. But I'm not the one who might have to get up in the middle of the night to do it, and they might have gotten complaints about the research items changing, if they did it a day earlier. While i've never seen the invicible inventory, if you had tanks in reserve, you might have sent them along a different path- just like you lose when your leutenant dies, you win when the dark lord dies, no matter how many tanks/buildings are still standing
