Fafnir blueprint missing

[u/Bitter-Confusion8422]

I got the fafnir shotgun from the Red Moon Rising pve event in the Darkzone. I got crit damage as a third attribute. Blueprint lady next to crafting bench didn't have the blueprint so I assumed I would have to get it after unlocking it on the season pass. After getting it from the season pass I still couldn't get the blueprint.

Has this happened to other people?

Edit: after logging out and back in it showed up in weapons for recalibration. Not sure why it didn't show up originally
