There appears to be an issue with block collision because of the height of farmland, it makes it so that you can't walk from block to block, you get stuck. I can't really describe this in a way that would be useful to a programmer lol.
If you walk on farmland you'll see what I mean, but I've only tested it on my server, I cannot say if it's the same in singleplayer.
This may have already been reported but just in case.
