Weapons that I unlock / extract a pattern for are not appearing at The Relic on Mars when I look to shape a new version.
This last happened yesterday when using 'Succession' sniper rifle from the Deep Stone Crypt raid. I shot things until I was able to extract a pattern and it was confirmed on screen that a pattern was extracted.
I then went to Mars to 'shape' a new version, and the weapon was not unlocked. I believe this has been happening to me for a while, but I just haven't been bothered about it until now.
It appears that no new weapons that I extract patterns for will appear there...
You need to check the overall progress for a given weapon pattern as some take up to 5 attunements to fully unlock the pattern.
you might be confusing the pattern progress notification with the actual unlocked triumph that is shown on the screen.
The pattern progress notification is a small notification that usually appears on the top right side of the screen while the unlocked triumph usually appears at the bottom of the screen.
Most weapons require multiple deepsight patterns to be extracted in order to craft them at the Relic. For example, Succession (and all other DSC weapons) require 5 extractions.
