Just noting here that the PF Hopper does not function on Potato. I set it up, and Flonsh and I both tested it, and no carrots (what we were breaking) automatically went into the chest the hopper was attached to. Note, I am currently playing on Potato using 1.15.2, not the latest release, but I don't know if that matters or not. Sincerely, InfamousDot
Hi, it seems like it functions correctly for me when I've tested it. Are you sure you placed the hopper and carrot in the same chunk?
I just set it back up and tested it again, to no avail. It is within the chunk borders of the nether wart I was just harvesting.
