The sheep are still in the Terrain Editor. They can be used in AvA/SEA terrains or easily placed back into the standard clutter if HTC so wishes. I would like to add some flocks to one of my WW1 terrains-in-progress, but I don't know if WW1 terrains fall under the same category as AvA/SEA terrain (where customizing is allowed) or as a standard MA terrain. I'm hoping it falls into the AvA/SEA type, since just its small size does not adhere to MA terrain rules.
