Okay, got some more info about the glitched mission - Keep Your Insides Inside
I joined a PT2 online game and had a team of 4 - Lvl38, Lvl43, Lvl46, Lvl50 - doing the Shock Crystal mission in the Lost Cave. When we turned it in, we all got KYII except for the Lvl38. For the Lvl38, it was his first time doing the PT2 Arid Badlands missions with that character. But, for the the rest of us, our characters had already progressed past the Arid Badlands before joining the game.
So ... it seems if you go back to the Arid Badlands with someone who's going through for the first time, you're likely to get KYII. BTW, I'm seeing a lot of KYII online games lately. -- MeMadeIt 18:41, May 22, 2010 (UTC)
I have had some success avoiding the problem entirely by first selecting Playthrough 1 in Single Player, saving, then going online with my now "P1" character. I got a better selection of games to join that way as well. Fryguy42 06:35, May 28, 2010 (UTC)
I was able to complete this mission by having both it and the "Fix'er Upper" missions both available at the same time. I entered a freshly hosted "Fresh off the bus" online game, then proceeded to take the steps necessary to complete the "Fix'er Upper" mission. However, when I bought the shield and tried to get credit for the mission... I ended up getting credit for the "Keep your insides inside" mission instead. At this point, I exited the game (host booted me actually). The next time I logged in, I was stuck because the mission "Fix'er Upper" was still active, but could not be completed. This is a bad bug because there is no way to get further in the storyline without being able to complete this mission. (Had a miniature panic attack actually.) In order to fix this, I had to join yet another freshly hosted online game where they were on the mission "Fix'er Upper". This time, when a team member bought the shield and turned the mission in for credit... I ended up getting credit for the "Fix'er Upper" mission and was able to continue on with the storyline.Atelophobic 20:07, September 28, 2010 (UTC)
