This game is really glitchy, i'm beyond frustrated right now.
Just Pure Platinum'd 1-B after having to restart it because mission 7 wouldn't show up for no reason. So I did up to mission 7 and went back to the Kahkoo-Regah and got PP on that.
When I went back out mission 6 started but only the missiles were coming down, no enemies spawned so I just proceeded with the rest of the operation. This is what I was rewarded with for all my troubles.
Apparently getting Pure Platinum on all missions awards with you with a Consolation prize. This is infuriating. I understand that they were putting stuff in up to the last minute and I appreciate all the hard work that went into this but as a player this kind of stuff is the WORST. Not to mention glitches that ruin your chances of ever having a complete save file.... what a mess =(
