I'm not sure if this is a _bug_ or not, but it seems rather odd...

My first village is done except for 1 award - a villager living to 90yrs old. I check in on my tribe once a day, and after the new dead villagers are buried, I check the Roster of the Dead and have noticed an odd pattern. My villagers are dying in groups at the same age.

Today I had 9 new dead villagers who all died at 79. Yesterday it was 8 at 81, the day before 12 at 77, etc etc. I have 185 dead villagers and since about #40, this has been happening. Something seems not right with that.
