Weird, I replayed your simulation and you lose a planet at 336 years (89m score). I wonder if the game was subtly tweaked since you played it, or maybe your browser produced slightly different results than mine.

Apparently these systems (dwarf-n-habitables) are hard to record correctly: http://www.stefanom.org/2000000-systems-played

I just observed the same result (89m 336y).
