UPDATE (22/03/24, 17:00 PM GMT): While it still doesn't look to have been addressed by Arrowhead, the consensus on this weird happening seems to to be that the successful order completion messages were most likely a bug of some kind, as the community definitely didn't achieve the objective in time.
Uh, ok, so this is gonna be a weird one. After Helldivers 2 have spent the last little bit all preparing to fail the game's latest major order - likely due to all of the issues that've been plaguing the game this week - it looks like they've now gotten conflicting reports as to whether they have or not.
Yeah, they're just as confused as you are. And I don't just mean the folks who've been having to hope that the game's mechs will someday become idiot proof. Though, to be honest, given the problems that've been afflicting the game's galactic war liberation percentages, this might not be that surprising.
