You currently have two Titans and a Warlock on your account. I'm assuming you created a second Titan to test out to see if it was your character, but that, in and of itself, can cause an issue for having two characters of the same class at the same time (as only one can get the Prime benefit). [u]The Prime Attunement is a buff granted based on an allotment of Prime engrams over a certain amount of time. If you don't have the Prime Attunement buff, it simply means that that character is currently at or has exceeded the allowed amount of Prime Engrams over the amount of time that the system tracks.[/u] Purely for example sake, let us say that you're allowed one Prime Engram a day. So after you pick one up, the Prime Attunement buff would normally disappear for 24 hours, then come back. If, however, through accident or purposeful thought, a Prime Engram drops and you continue an activity without picking it up, then you'll still have the Prime Attunement buff, which means another can drop. Let us say it does drop, so you go to orbit and find two sitting in your Postmaster; now you've gained 2 Prime Engrams in that tracked 24 hour period. This means it will be 2 days before you get the Prime Attunement buff back, as you're over the allowed amount. Now, let us say, purely for example, you're allowed 3 Prime Engrams in a 7-day period, that means if you play hard for a day and get all 3 Prime Engrams over that first day, that you'll still have to wait 7 days for the Buff to come back because until that 7 day period is out of tracking, you'll still be at or exceeding the 3 Engrams per 7 Days. If, however, you get one on day 1, then one on day 2, then one on day 3, each of those lands through a different 7 day period, so the Buff will remain after the first two, then disappear for the next 4 days and come back until you pick up another Engram. It sounds more complicated than it actually is. - [u]So, all in all, don't be alarmed if your Prime Attunement buff disappears, it just means you're at the allotted amount of Prime Engrams you're supposed to have been given, and it will stay gone until you're back under the amount you're supposed to have. Once you're back under, it'll reappear, and you'll be able to pick up more Prime Engrams.[/u] There are no known issues concerning the Prime Attunement buff. I would highly suggest deleting your extra Titan prior to the Tuesday weekly reset; as long as you have a second Titan, it can cause you other issues with receiving rewards, Prime Engrams included.
