Silly yellow names! This is why we have every right to tell you what a lausy job you are doing! Testing would go a long way in preventing you and the other yellow names from looking stupid in the future!
Happened to me. I have already unlocked both rounds of borg prothstetics and the mk xii rifles. I unlocked the purple ones first, and when they didn't appear I assumed they were under effects of the same bug that the prothstecics were before, where you had to unlock both to see them. That did not help in this case. I have no doffs available to me, and the projects have disappeared from my available project list.
Edit: Yes, I do have some borg doffs from the old system, as well. That may be relevant.
I once again match my character. Behold the power of PINK!
Same thing just happened to me on both the rare and very rare tiers. These were going to be my first store unlocks. It just resolved and didn't offer anything to accept. Kinda sucks cause that was a lot of marks and commodities to throw into oblivion
