My son just got Minecraft and he built a base with some other guys. One of them built a treehouse. I was there helping my son on a project and he decided to set a sheep on fire not realizing that the sheep would set everything around him fire. In other words the treehouse was burnt to the ground. We ran around doing our best to put it out but the treehouse was lost. I don't know how he had it set up or I would fix it. My son doesn't know which of his friends the house belonged to or I would message him myself. I've been on the server a long time and now I'm worried we may get banned. Any advice?
