I would like it so that if a food item is in sterile atmosphere and a deep freeze. it would slowly turn more and more fresh and reach 100% freshness after a few weeks. The reason is the sheer impossibility for mechanical transportation to move food any distance without it being slightly less fresh, say at 90%, and that makes it not merge with stacks at 100% or 99% hauled by dupes. It is especially annoying due to grubfruit already struggling to merge due to its weight and uncookable nature without sucrose.
There are probably 2 ways to make it work:
1) add a status effect to all food of +1% freshness/cycle, or
2) modify the deep freeze freshness % per cycle from 0% to +1%.
I think the second one is probably easier, as it should just be changing one number from 0 to 1, right? I dunno how to mod stuff but I would accept pointers to how to get started making my own mod, i just have no idea how to get started.
