Mod doesn't appear to work with this mod when right-clicking crops to harvest:

Its impossible to place seeds within the farming station in EnderIO:

It is also impossible to use bonemeal, perhaps adding a special bonemeal that is harder to obtain to balance out using the crops would work better than normal bonemeal.

Forge: 1.12.2-forge1.12.2-14.23.3.2675
Mod: Attained+Drops-1.12.2-3.7.3

1. Right click harvesting is a configuration option. Other mods will not be able to provide this functionality since Attained Drops are not "normal" plants by minecraft's standards.
2. Probably will remain that way, as Attained does not follow "normal" plant rules.
3. No bonemeal is intended. It will remain that way.
