[2021] Stellaris - [3.1 Lem] [22a5] Clone army origin lithoids have a default lithoid starting age, resulting in a really short lifespans

A regular biological pop with no lifespan changing traits will tend to have a chance to die after 80. The Lithoid traits adds +50 years, and the Clone Soldier trait adds -40 leader lifespan. So I would expect a lithoid species with the Clone Army origin to have a chance to die after 90 years.  

Yeah regular clones start about 10 years old and live until about 40, lithoids start about 60 and live to about 90. Either way you get about 30-40 years lifespan out of your clones, as intended.
