This isn't actually a bug though, but by design. If you take a look at the Neoseeker interview (there's a threat with a link on the front page), Frogboy actually mentions this specific thing.

It's weird, but I think it was done because people playing smaller maps would never get a chance to deal with the Dynasty system. On the one hand you could say "Well of course, they're playing short games", but I generally have the opinion that all core features should be available for all ways of play. If someone only likes shorter games on smaller maps, there's no real reason why they shouldn't be able to dabble with the Dynasty system. Gameplay trumps realism in this case, I think.

Well, make everyone age faster in small games, then? It's that simple. =p

I guess what a Turn equates to in terms of Time has yet to be nailed down?

I had heard rumors of 1 Turn = 1 Year but your #'s don't bear that out for sure.

I prefer a Turn to be a Turn, and Aging should just be done to accommodate the use of the Dynasty system... as previously noted above.

A SoV has Magical powers that are passed on to the children, they mature quickly, then have long prosperous lives...

Your Offspring already have "Essence", the special component.

As such, they too are special and I do not see that changing anytime soon...

I thought Essence was just "life force", hence the usage of the Life magic symbol. So, we can drain our offspring of their life force in order to fuel the war machine. =D

This.
