Hey there!

I've recently tried to set up a berry bush farm using foxes, however after waiting sometime and even going afk to let the foxes harvest over night, they didn't shake off any of the berries. I looked for possible solutions and found MobGriefing was the most common problem, along with light levels and other farm animals to keep the foxes awake, however MobGriefing was set to true and the light levels were fine too. Unfortunately I have never made one of these farms before and I am unaware of when this bug my have started to occur. If it helps the platform I play on is windows 10 bedrock and I have only seen fixes for Java. 

Thanks for you help and time!
