I have no idea where to report server bugs, so I'll do it here. As of now, I cannot kill any of the animals that spawn at /warp animal. This is important because many new players may get frustrated without having a supply of food, and they may quit because of that. This leads to loss of income, etc. Dough and two other players in-game confirmed that /warp animal is protected under world guard, and this is what is preventing them from killing the animals.
