Kuze bug: we've experienced in an online mission of su33s. After changing direction of the Kuze you cant land on it. As if only the texture was turning, we couldnt land on it anymore.
As for random failures: Of course there is the option to turn it off (by default), so who dont want to use them dont have to. But i would like to, and i can set the failures to random, everything is fine, except that every player plane gets the failure at once :( It would have been so easy for ED to implement this to player planes separately. Its just stupid like the friendly fire bug :(
