Rank 6 Mastery Test Broken?

[aNeglectedKitten]

I can't progress past past it  because after using my boltor prime for 3 orbs, they all dissapear. I have tried running different frames and stuff, but it still doesn't change it. I haven't changed my bltor rpime to something else, but I will. Its just I've tried 3 imes and it still doesn't work...

Try a hitscan weapon instead. I mean, those balls doesn't need an ogris rocket to go down, so you might buy a MK1-Braton to do it. No, wait, don't, actually. But something that isn't shooting bolts.
