When ever I jump while on top of cocoa bean that's attached to a jungle block, whether freshly planted or ready to be picked, i teleport to the top of what I'm standing on. I included a video of it, I can jump and place cocoa beans sometimes.. I tried reseting my computer, my internet, and destroyed the jungle blocks and replaced them and the bug still happens. My internet connect is strong on everything else in my house and while I'm listening to music on YouTube, so i know it isn't a lagging connection!
Maybe it's because your cocoa blocks are melons and lava pumpkins and your beans are poop. I think it's something to do with the fact it's not a solid block and also that AntiCheat really sucks (as seen in chat in your video).
