I am not sure if this belongs here or somewhere else.

I am working on a mod (almost finished play testing!) in which one of the final items has 19 ingredients.

It turns out the recycler only has 12 output slots, so only 12 out of 19 ingredients will be retrieved. The rest just disappears into nothingness.
This is not random, always the same items are missing, making quality upcycling impossible.

I found a solution/work around, in the data-updates.lua I include:
This seems to fix it.

I hope this helps someone.

This behavior was previously determined to be Not a Bug. There are 12 products of the Scrap recycling recipe, so if your Mod adds more Ingredients/Products to a Recipe then this number will indeed need to be changed to match.

Good Luck!
