Im on a server, which generally has 2-10 players on. I have a zombie pigman farm, and guardian farm, and both seem to be affected similarly. When a specific player is on, its like chunks around me go onto peaceful. I might get a zombie or two a night, and only one group of pigmen spawn every 10 seconds or so.

This happens when there are just the two of us, or the server is full. With the same numbers of players, but not them, rates return to normal, and they live in the same area as another on the server so I dont think its to do with them needing to light their area up. Any idea what this could be? Its really affecting my rates.
