I kamikazied five times to complete "Downfall", only to get stuck again a few missions later on "Purpose Calling".
On "Downfall", radar wasn't the problem; I had the radar on infinity range and I could see the green blip. The problem was, I flew to the blip and there was nothing there.
On "Purpose Calling", it's a different problem. I can find the source of the radar blips: (a couple Shivan fighter wings and... some large capship that I can't see enough of to identify
. Trouble is, I can fly around them, shoot them, ram them, lead my wingmen to them, et cetera, and nothing happens. No "Oh no, Shivans!", no "Let's get out of here!"; the ships stay stealthy and my allies ignore them. Whatever was supposed to happen when I found the shivans isn't happening.
EDIT: Wait... I tried "Downfall" for the Xth time, and this time I wandered around more. The reason I didn't find anything at the blip is...
The blip is a Knossos. I should have though of it earlier: the briefing on the next mission revealed that it was a Knossos, but of course on a knossos there's nothing at the center blip.
However, I still can't complete the mission, for the same reason that I can't complete "Purpose Calling": I can fly right to the thing and nothing happens. it seems like it was the same problem both times. Ransom, if you're there, any idea what the problem is?
I just tried both these missions, after seeing your review. Both of these are cutscene missions -- there is literally nothing for the player to do. In "Downfall", progress is triggered by Alpha 2 moving to the blip -- it has nothing to do at all with your own actions. I just flew slowly behind Alpha 2 and everything went fine (under 3.7.1 BP Debug). In "Purpose Calling" the event is triggered by when the distance of Alpha wing as a whole to the unknown object is less than 900 meters. The mission wants you to do nothing but fly around slowly -- if you go off on your own other ships in Alpha wing will get too far away from the unknown and the event will never trigger.
Hope this helps.
Weeeeeird. On Downfall, Alpha 2 Never seemed to reach the blip until I downgraded (I might have borked it by giving Alpha wing orders, but I don't
thinkI gave any orders after the first 2-3 tries out of however many. On Purpose calling, I had Alpha wing cover me as I flew within spitting distance of the Big Bad, and nothing happened, again until I downgraded. With this knowledge I'll try those missions again on 3.6.18 and see what happens.
EDIT: Still no luck.
Downfall: Alpha 2 doesn't even try to get to the blip. Alpha 2's orders are "Guard Alpha 1", Alpha 3's orders are "Guard Alpha 2", and they just follow me around in series. I could try banging Alpha 2 into the blip, but... more or less impossible.
Purpose Calling: I told Alpha to Form on My Wing, and then started ramming the... big thing. Nothing happened. (note... considering it's some 5.5 klicks long, maybe we needed to get to get within 900 meters of its CENTER... still more or less impossible.
Regardless, both missions worked in 3.6.12
