Were the drop rates for mission discovery items recently lowered, perhaps two or three days ago? I have been running three companions pretty much continuously on slicing, two on the two level 6 lockbox missions and one on the rich level 5. Seems like as of a couple days ago, I'm getting far fewer mission discovery returns. I was gathering perhaps 3-4 a day, and over the last two days I have received exactly one of them. On the other hand, perhaps I've just had a streak of bad luck.
