Hi.
Not sure if this is just in my modpack. I will test after i write it all down here.

1. after changing the ingredient/result amount of any recipe without clicking on a different number, the change wont be saved.
2. all changes to "probability", "percent spoiled" and "amount range" wont get saved at all.
3. existing ingredients and results that contain a probability or amount range cant be edited nor removed.

thats all ive found so far.

ok, i just changed a few recipes and got this crash: https://prnt.sc/52VuRxZSahQe

Ok.
I just checked and when i only have this mod active, i can change the "amount range" and "percent spoiled" but the "probability" still cant be changed. Also all changes to existing items arent saved. I have to remove that item and then add the one I want for that recipe.
And again. Just changed a few recipes and got this crash: https://prnt.sc/XtQuDrTBr28P
here are the recipes I changed:

This is intended, you have to press enter to confirm a number change, and if you confirm before you do that you lose the unfinished change.

all changes to "probability", "percent spoiled" and "amount range" wont get saved at all.

This was the last thing I looked at, and I wasn't able to reproduce anything. Probably because whatever was happening involved the changes I made to fix the other things, so hopefully it's not an issue now. If it still is, let me know.

existing ingredients and results that contain a probability or amount range cant be edited nor removed.

This was indeed a bug, I forgot to handle removing properties from ingredients/products. This is fixed in 0.1.4.

I got another report about this and that's also been fixed.

Thanks for finding all of that in one go, hopefully there aren't any other issues.
