RETCON: Party Hard

RETCON stands for Retroactive Continuity. Which usually a purposeful change in an early part of a storyline. In this case, it's intended to fill in some holes.

So how the hell did those numerous JuJi clones that Chiba supposedly beat up get there? ([link] and [link])

What happened her was that a group of clones decided to party and get wasted back at base camp. They took a truck and went for a drunken joyride until they ran into the HKs and into the giant hole. They encountered Chiba an then woke up right before O.D. assaulted her with his chainsaw blade.
