I just did Puck 3 times in challenging mode, 2 times in normal, Puck won't drop the ****ing blueprint.
I'm getting really tired of your **** Ubisoft. I support you since day 1, but right now I'm reaching my limits. I managed to deal with your timegating BS even tho I am allergic to such ********, but now I have to deal with another full rotation of probably one month for a ****ING WEAPON. Really ?
Check if you have all of the rifle parts, there is an issue with parts going missing from peoples' inventories (like the part i got from doing the Roosevelt Island invaded mission). I do wish that those that had all of the parts required before TU3 would get the blueprint for free, rather than having to wait for the Grand Washington mission to come around next time. Consider it compensation for taking the rifle parts from people just before they were able to get the blueprint.
I don't have all the parts, but a clan mate showed me a screenshot of him having the blueprint but not all the parts. So I am kinda confused about this being another Ubisoft ****up or whatever, it's just making me kinda mad all this hassle for a weapon, all that timegating, waiting, jesus christ this is ridiculous.
Should be a bug, because you're not getting the blueprint without having every part.. Get all the parts, than get the blueprint. That's how it works... I had it myself dropping on hard difficult in the invaded mission. My advice, get the other parts first before trying to get the blueprint, because relying on a bug to get the blueprint will not get you anywhere.
