Spent the past day trying to pass 5/5/5, and have been unable to so far. The configs are set to 10/10/10.

Created a modpack with just JEI, Agricraft a19 and Mystical Agriculture and couldn't pass 3/3/3.

Also tried duplicating a modpack in which getting 10/10/10 was previously possible, updated Agricraft and InfinityLib within the modpack and still 3/3/3 seemed to be the max achievable.

Hi! I've uploaded a preview of the a20 release, which contains the fix for this stat increase problem. If you get a chance to try it out, let me know. Any feedback will be great. :)

@CodesCubesAndCrashes Tried using it and I have successfully managed to get some 10/10/10 potatoes
