I am using forge:10.13.3.1374, along with all the recommended CoFH mods and MFR.
Forestry: 3.5.4
*I have Optifine/Fastcraft.

The bug I am encountering is a cross-mod bug between Forestry and the Fruit Picker. When you place a Fruit picker in from of a tree such as a cherry tree, you expect it to PICK cherries. However, the fruit picker doesn't stop. It continuously seems to generate cherries, without them even being picked from the tree. Below are two screenshots taken about a minute apart.
