Scourge sometimes doesn't let you fire upon retrieving it after throwing it. No other weapons were in my loadout; I'm unsure if that affects it. I did try swapping to gear in my gear wheel, but that didn't work.
Encountered a bug while doing a Neo Fissure on Ani. When we got to the reward selection screen, we encountered this: Had to alt-f4 to get out of the mission... not to mention I probably got something I didn't want or didn't get anything.
