OK after testing it, I don't know if its a bug or intentional but when you use F3 (Inf. Pop) it sets the military troops to zero which is good but workers as zero as well which is bad, you won't be able to create any more workers after using F3. The only way around this is to first create all 60 workers max allowed and after that use F3. I checked this on Skirmish mode and Free Game mode but I'm guessing its the same in campaign mode as well.
Can you implement a reveal map option as well in future update? That would be nice because console commands doesn't work in Skirmish and Free Game modes.
