It's time again for a little tweak to the Warmachine and Hordes rules. Privateer Press has posted a new Update and Errata list. Though it's a small update, it does deal with Colossals, which are the biggest figures on the table. So, you might want to take a look.
From the update:
This is a small update, including changes to the rules governing the rule of least disturbance, colossals, battle engines, gargantuans, and new rules for colossal horrors. Four cards also received updates—one due to an oversight and the other three for rules clarity.
