I am going to orbit before the scoreboard goes away (when I would be put into orbit waiting for the next match). So yes, the scoreboard is still on the screen when I use the O key to go to to orbit. But sometimes the problem does not occur in this scenario (just now, my 4th IB match while trying to get 3 counted), so sometimes it gets it right.
At least when we get -blam!- out of a reward at the end of a mission (e.g. Presage), it's because we didn't wait until the "Mission Complete" message showed up. I get that. But I don't see any visual cues in the Crucible scoreboard page that would indicate it's not "done" yet.
LOL, I didn't know g - y - p - p - e - d was a bad word. Learn something new every day.
