EnderCore does not allow harvesting of crops that are more than one block tall such as corn (Simple Corn) and hemp (Immersive Engineering). I can add a block from either of those crops to the cropConfig.json file, but it will replace the individual block and plant a new crop in that space. With Simple Corn I have added simplecorn:corn with meta:9, 10 and 11. I can right click on any part of the mature corn plant and it will harvest that block and plant corn in that space, bottom middle or top. Is there a way to check above and below the block to remove all blocks from that crop and plant in the dirt at the bottom?

This functionality is only meant to add right-click harvesting to the vanilla stuff because it is more or less a standard thing nowadays. Modded plants are expected to do their own right-click harvesting.
