I have been searching all over the internet for the last hours or two, attempting to find some kind of documentation or explanation for the Crop Harvester and agricultural blocks in general. There is not a single piece of documentation available for the current GUI that IC2C uses for the agricultural blocks, all the videos and guides made use (presumably) IC2 not IC2C and thus have a different GUI's which make it impossible to use these blocks, cutting out several core pieces of functionality within the mod. I would vastly appreciate it if someone could reply/comment with some explanation for the IC2C agricultural blocks (specifically the Crop Harvester although a general explanation would also be helpful) or a link to an in-date guide which is relevant.
