Sorry to be such a bother, but I'm still having trouble understanding aging. I'm playing the long game, historic setting, as the red player. Three times now I've ended up with the eastern roman empire rocketing up to Age lvl 3 in about 15 years. I assume I'm doing something wrong since the Eastern Roman Empire is only lvl 2 at the start of a later scenario that begins in the next century. However, I can't for the life of me figure out what exactly I'm doing wrong.
Is rapid growth detrimental to a country's Age? In two of the three games I managed to add large tracts of land to the Eastern Roman Empire (four provinces in one game, six in another) and in the last game I added one or two provinces.
Could it be the revolts? I sometimes forget to visit each revolting province to revert them back to my rule. In one particular case I had a province go something like six years before I noticed it.
Or am I simply reading too much into the age level? Maybe this rapid aging is offset by something later in the game that reduces aging - sort of like an Imperial Botox Stratagem.
ps. I've also noticed a small problem with churches and cathedrals. The rules say that you must have a church present to build a cathedral, but this is actually reversed in the game. You can only build a cathedral if you don't have a church.
