Would it also be possible to have compatability with both of those machines to fully automate the harvesting process? Or does Create do some funky stuff, making it impossible?

Version that does not crash the game:
quality_food-1.20.1-1.7.3-all.zip

Added compatibility so quality gets applied when cooking with a fan (was that what you meant?) and through harvesting
Also added sth. so harvesting should retain quality when things get re-planted

Don't know much about create, so I only was able to test the fan one
quality_food-1.20.1-1.7.3-all.zip

Yes, that is exactly it. Thank you this is amazing!
