Hi! Thank you Timo, I can not believe I missed this one....
This fixes a commit back at rev 14041.
With out starting a review in real world history,, once an enemy gains control the first thing they do is erase history. New eras evolve and build on top of old ones. Our old world ruins are a good example. Look at Cuzco, Greece and Rome. You see them now uncovering the past.
Thanks again! James
