[TFTV] Vidyar Grenade Launcher Research Not Showing Up After Acidworm Autopsy

Relatively self-explanatory. I completed the Acidworm autopsy but I don't see the research for the Vidyar Grenade Launcher ("Agile Grenade Launcher Development" technology) in research. The techs for the Goliath GL-2, Slamstrike, and Hawk have all shown up without issue.
