Hi MissKitty,
GBU2.
I 'revised" my " 31 crew plan", as I found out, not much room in science, to 3 sections:

8 in building
10 in farming
10 in science

And "if/when" needed, I'll "reborn" my king to be the healer, at the age of 14, in Chapter 2.

I have 3 "elderly crew members" and am leaving them in healing.
GBU and yours.
