Loving the fact that you enjoy the premise, I was not sure if I took it a bit too far from farming. And thanks for the compliments as well!
The number of tools is tied to the current map seed, so you either replayed one where you don’t get a fork, or got unlucky with generation. Each seed will spawn 0-4 durability for each tool, which is slightly weighed towards getting 1 and 2.
Edit: looked into this, there was an issue with seed generation on “New Field”, so you probably replayed the same stage twice. Sorry for the inconvinience, fixed!
