[1.0] Animals competing for grass stack up

[FrodoOf9Fingers]

On a upper medium sized mountain ocean river  temperate map the grass doesn't grow fast enough for animals on map. At around fall of the first year (no cold snaps), competition for food is high, leading to lots of animals trying to eat the same piece of food. They will even stack up on each other to do so. Might be intended, but I haven't seen a note about it.
