I was trying to reduce the amount of biter eggs and seeds that were necessary for both the jellynut and yumako overgrowth soil recipes. At first I just reduced the amount of seeds, which worked. Later, I wanted to reduce the amount of eggs, but every time I do it, the previous value that I had edited (in this case, the seeds) goes back to the original value after I copy/paste the exchange string and restart the game . So for example, the first time that I set the biter eggs to a lower value, the amount of seeds went back to normal, and then when I go to edit the seeds value, the amount of biter eggs goes back to normal.

To be clear - setting up the recipe in the UI at least appears to work fine. I can set the values the way I want, I click "confirm", and I open them back up and it seems like they've been properly saved. The issue seems to be during the exchange string generation / loading phase.

Let me know if there's anything that I can do to help debug this further.

Whew, this one was hard to track down. There was a slight issue with opening a tweak that overwrote the stored original recipe data, so it thought whatever first changes you made were what the original recipe had, making it not store them to be transferred back to prototype stage, therefore effectively removing your first changes. Thanks for reporting, fixed in 0.1.10
