So, I was just speaking to one of the developers of the craftbook plugin (an amazing plugin that has been in minecraft for many years and versions) and he mentioned that the version of the plugin that minehut was using was quite old, as well as being a snapshot. (I'd been having trouble farming netherwart, so I contacted him, and that was the answer he gave me.)

Link to the video of my problem, should you want to see it. (It will likely get taken down after a month to a few months)
