Another odd thing

This is the second odd thing on my realm now let me try to explain it. I was using my raid farm which is near my tower and the pillagers always came left of the farm never the right of the farm. After I was done using the raid farm I found my crop farm that’s at the bottom of my tower harvested. Not trampled, harvested. At first I thought they trampled it and the raiders came from the right but I remembered that they came from the left. So I thought it was another player but no players logged on while I was in the game. What do you think happened?
