when i am trying to get the third catapult to come up it will come up two thirds of the way. the first game i played i had the second one up and the third on was already up there were no monsters around it and no men trying to get it up. i started a second game. this time i fought off monsters. the guys were there getting it up. this time i saw the catapult coming up. again only two thirds. went to get the last one up came back two guys on the ropes but no catapult.
