Hello there, Thanks for the report. Tier 5 weapons are supposed to gain their enhanced origin trait along with the rest of the Tier 5 sandbox upgrades. There have also already been other Tier 5 bugs where weapons were missing their enhanced origin traits or other expected enhancements, including a recent live issue where Tier 5 dungeon weapons could lose an origin trait instead of gaining the upgraded version. So if your Firefright upgraded to Tier 5 and only the origin trait failed to switch to its enhanced version while the other perks updated normally, that looks like a bug rather than expected behavior. If you are able to record a video, you can upload it to a site like Youtube, link it to us here, and we'll be glad to take a closer look.
