1. you cant hit animals at /warp animal and 2. theres tons of rainbow sheep at /warp animal that is causing the server tons of lag.
There's not a lot of players complaining about the lag but there are a bunch of greenies and lower ranks complaining that they can't get food.
Ask a fmod or smod if they can despawn the mobs. I'm pretty sure they can. Ask an online one to do so.
