The penguins in the biome Twilight Glacier are causing a huge amount of frame rate lag. Either you're rendering the penguins in like 20 different sections or the penguin's AI is way more complex than meets the eye. Penguins are evil though so I understand if this is an intended mechanic.

The lastest log does not mention anything about rendering or penguins or Twilight Forest so I did not include it, but I can get it to you if you need it.

##Steps to reproduce:

1. Go to the biome with all the evil penguins. (Twilight Glacier)

##What I expected to happen:

I expected the game to be playable.

##What happened instead:

My frames per second turned into seconds per frame.

run a profiler on both sides using /debug, Sampler, or WarmRoast and post the results

Using sampler helped me identify the culprit as roughmobs, which the author admits has performance issues.

I can't upload .nps here, so here is a screenshot:

One additional possible clue... when I removed roughmobs to confirm it as the culprit and loaded in the world, all the penguins I could see furiously flapped their arms for about 5 seconds and then settled down, like they were catching up on something.

so this isn't a TF issue then (the penguin AI is quite tame, really, not much more intense than a normal vanilla animal)
