Despite recent fixes to catapults it seems that they still have some problems. I spent almost the entire Yruma castle tearing that place to pieces, but after the 2nd catapult went down It became quite a bit harder to accurately fire on the castle. For whatever reason the 3rd catapult, which was on slightly more of a slope than the first two was firing as if the block was far back and also going a bit to the right and somewhat random with the distance. This continued with the catapult and seemed to be getting worse until I suggested using it as a Trojan catapult while another one was built, that one also had problems. I moved over to one that the other guys had just been using normally, and it seemed to be having this problem as well. I then tried an abandoned catapult that was below on flat ground, when I hit release the stone went about 50ft straight up, and came back down destroying the catapult. I then went back to use the last catapult as best I could for the rest of the battle.
