Troll caves

[bardliam]

This is my first Orbis game, and three times now I've had to fort up in my city while troll razed my lands, because I can't remove their caves! Is there any way to get rid of the caves?

Workers can remove them with Construction. Also, Hunters are pretty good against trolls

Trolls are sweet
They die so easily... free xp for Your units

Sitting a unit on the troll cave prevents the spawning.
