I thought I’d be very smart by not turning the mission in where the guy that sells you weapons shows you the elemental stuff. I played with the corrosive weapon for a while then restarted the game. The weapon was gone afterwards. Then I did it with the slag weapon. But again, after restarting the weapon was gone. I am now afraid to pick up the Grog Nozzle because I only have one chance there. Is this a bug or is it normal? Idk if this is important but I played Koop and I was the host. I also never dropped the weapon.
Thank you for your help!
Edit: With restart I meant quitting and saving (not resetting my playthrough)
