I finally got griefed. He/she burnt down one house and did some minor damage to my mob grinder. He/She then did minor sub-par repairs to the grinder although it was still deactivated by torches and messed up water works. Change of heart, or plans on using the grinder? Thanks. I think.
It has been about a week since I had last been to the grinder. So I can't pinpoint a timeline. I'd like to think they have a conscious. Maybe two people. One griefed the other repaired. I don't know.
