A player on the Enigmatica 2 server just had all his IC2 machines taken out by a pair of goats. Apparently they're little headbutting demons. So be careful about letting those cute little buggers just wander around.
Unfortunatly, this is true.... as i was the player this happened too... Please be aware that Animals from anamania are not cute and cuddly, they will destroy your base!!! YOU HAVE BEEN WARNED!!
