We get that it's his server, but in a competitive field (mini-empires), he's clearly using this as an advantage over other players. He refused to allow other user to keep their builds, even though he would be loading the same map, so to say. I was present. I support this.
Even if you may think that this is not drama-worthy, I at least say to take it as a warning. If you want to compete with this guy, just be aware that he will not stand for a level playing field. (People RPing said they had fully utilized antimatter weapons in the equivalent of the year 2010) and mass produced them. This went ignored even after he and his admin were called out for not moderating it.
