Confirmed for 1.14.2 release. Cow following player carrying wheat gets stuck on seagrass and starts spinning.
I had this problem today, Feb 8, 2017 c. 6pm Eastern Time. I also had it a couple days ago.
Windows 7 SP1.
Maybe the updater isn't ignoring the read-only flag on folders? It should ignore that flag on folders, honor it only on files.
