im playing a custom pack and sorta piecing it together and for some reason if I let a crop stick empty for id say no more than 10 seconds a random mystical agriculture crop will pop into the crop sticks. using the most current version of agricraft and mystical agriculture

This is a known issue with the default JSON files. Go to config/agricraft/json/defaults/mod_mysticalagriculture/**/*_plant.json and set all the "spawn_chance" fields to 0.0, instead of the default 0.1.
