Two things...
1) Looks like there's a bug in the harvesting of fully grown plants.
I got one guy whose primary responsibility is growing. He has a bunch of other duties but his #1's are: Firefight, Patient, Flick and Grow. The first potato crop is ready and he walks out to the field, and then alternates between standing and harvesting. No potatoes actually GET harvested, and he doesn't move on to other tasks.
I've manually assigned the guy other tasks and he does those OK but NOT the harvest task. Any ideas?
2) Can you give me a hint on how to procure "synthetic materials?" Plastic, Rubber, Synthetic Fibers... none of these things seems readily obtainable through bootstrapping (using materials in every world and the production facilities one can make from them)
e.g. I finally made an aluminum bed.
Mine Steel
Make Steel Bar from steel.
Make Spare Part from Steel Bar
Mine Aluminum Ore,
make aluminum bars,
Make Aluminum Part for spare part and aluminum bars
Make bed from 1 spare part 2 aluminum parts
But I can't get started on anything that makes Plastic, Rubber, or Synthetic Fibers.
