After you have taken enough bases, factories for a country will move to the rear and announced. However...would it be more realistic if there was a delay for the moving of the factories?
As of now, once the factories move, they disappear and magically end up behind the lines. Could there be a delay based on the amount of sectors it has to "move"? One sector equals one minute delay.
So based on the map, if the factories are pushed back 10 sectors, there'll be a 10 minute delay before it appears there.
I ask this because just tonight, I was leading a mission to Rook's Strats when the factories suddenly moved back in an instant, right after our country took a base. We were only 2-3 minutes out and the whole mission went kaput (But we did divert to secondary targets, I'm just bummed out because that happened after a 20 minute flight). I think this might come off as a "Oh this happened to me, it's not fair, change it NAOZ!" wish, but when you think about it, it makes sense. Factories don't just magically lift themselves and fly 100+ KM to the back.
P.S. It was still an awesome mission and <S> to the Rooks that tried to intercept us.
