I have a farm on my survival world based on this design:
And it worked flawlessy. Up until a certain point. For no apparent reason (?) it no longer produces any golems. It seems as if only one or two villagers get provoked by the zombie, and, as far as I can see, it's usually the ones who are standing on the corners of their beds, not in their designated spot. Or, as you can see on the first attachment, they're too busy chatting to be provoked. As additional info, a raid took place some time ago that I triggered by accident. Maybe the farm stopped working after that. Please help, nobody knows what the problem might be here.
