Bumping, since my original post was rather unclear. Thanks for any ideas.

I have a Preferred level account with a few 450 slicers on it and i have never seen a single sliced tech part or crafting mission at all. I don't have any companions' affection maxed out yet, but that still leaves at least a 10% chance to crit. I've gotten crafting missions and tech parts on my subbed account toons with no affection either, that's not great, but still better than zero. I've bought an Artifact Authorization (on 2 toons) thinking that might impact it , but after days of running slicing missions i'm still just getting boxes. Anyone have any ideas what's going on, other than possibly the worst RNG run ever? I can't think subbing would make the difference, but that's the only option left i can think of...

I did this. I have a nice, shiny second BOfrickin'P hoverbike sitting in my cargo hold.
