Don't forget the construction site changes:
slightly reduced hit points
Which can be build:
Large Siege Tower (moveable, lower upper siege bridge) (Small siege tower is broken)
Healing Tent (use enter to heal)
Catapult (moveable, lower/release arm, moveable block/counterweight, can fire on every building to let it "sink" into the ground)
To build those place a construction site on the ground and read which type it is, throw construction material on it, but make sure you don't hit it with the throwing animation or any weapon which will render it "broken"
When completed the construct will raise from the ground and can be used.
Pecores build catapults yesterday on their siege server handicapping the attacker team though
EDIT: Ups i missed the .211 update completly :/
