Hmm...well, it didn't work out. My diligent villagers planted and watered those crops for 8 years of gametime, but still no sign of a harvest, and now they're all dead but one. Is there anything I could have been missing?
On another note, I may have come across a bug. One of my original adults was age-zapped down to 2. He was 6 when the tribe started work on the crops, and he turned 14 just before the last of them starved. Oddly, when the food ran out and everyone else's health began to decrease, he remained at full health. He's now continuing to do work and shows no sign of slowing. Was the magic potion supposed to make him immortal, or never need food again? Or will his health start to decline now that he has come of age?
I guess I'll have him continue watering those darned crops, to see if they ever grow. Or perhaps he'll wander through this village of corpses and become a lonely Master of all trades.
