I was a day one (or midnight launch) player of BLTPS on Steam PC version and wasn’t worried about finishing the game nor leveling up as much as the group of players I ran into in multi-player. I got hung up on Badass Challenges early on in the game after grinding on my BL2 characters BARs previously. Once I got to Red Belly and the infinite spawning midgets, I basically stopped story progression and leveling to earn as many weapon challenges as possible. I think the highest character I had was level 8 or something… Anyway, because of my dilly dallying with the challenges for so long, when they had released the Bloody Harvest Celebration in 2014 (see link)

the hightest weapon drop I could get for the Jack-O-Cannon was level 4!
Please someone in Gearbox land, re-release the Deadlift encounter this Halloween season so I can try for a higher level version of the weapon. I can’t be the only one who missed out. All the Handsome Jack Collection players, I’m looking at you! Make your voice heard if you feel the same.
