I think I just found a compatability issue ....and the solution!

Problem:
I was using a mod that added new vegetables ([XND] Xeo's Genetically Engineered Plants), but they were impossible to move or stockpile as they didnt appear on the list on the storage options.

Guessing that it had fallen through the cracks of the vegetables recategorization into raw grain, raw vegs and raw fruit.
I was about to suggest having modded vegs default to the raw vegs category.
But came to wonder, maybe it allready did something like this... and tested rearanging the mod order.
And it worked.

Solution:
Add mods that add foodstuffs BEFORE the RimCuisine mod.

I can't make pastries despite having the correct amounts of stuff and skill
