Hello, I've been trying to convert zombie villagers but the world is stuck on Easy. I have watched all the videos and did all the routines but when I tried changing it to Hard, the commands go through (and I have op'd and deop'd myself numerous times) but I type /difficulty and it still says Easy. I have sent command through the website, changed it from server settings, restarted, and done /difficulty hard and no results. Could I please get some help? Thanks!
