I’ll look into the separate fruit vacuum stuff later, but seeing as this is my first attempt at moding, and I know next to nothing about coding, it might be a bit. Main reason I think they did all fruit goes to vac fruit was to save on having to write out each recipe, and keep the crafting menu shorter, who knows.
Most things that seem odd I think was for ease of implementation initially, and understandably it is a lot of lines to make them each separate. Like the vitamin C levels of fruits, they aren’t set by hand to be increments of about 83, I may be wrong, but it seems it just pulls from the “healthy” level 1- 83, 2-166, etc. Which is why all the dried fruits have similar vitC, I just took a fraction of the base item, rather then setting them more accurate to real world. The other vitamins on them are, which is why your dried peaches for example will give you some good vitA, and some iron where the raw will not.
