I beat the Warrior on Playthrough 2 and now I start doing the side missions (I had obtained, but not started most of them on PT 2) for PT 2.5. My first mission was flame of the fire hawk and I got a lvl 50 Shield. However the second one I did was the booze run that gives you Moxxi's Rubi...however I am only getting a lvl 44 gun.
I checked my mission log and not all of the missions are level 50. To make sure I was on PT 2.5 I went out the the Southern Shelf and the bandits were level 49 (confirming PT 2.5 right?).
Accepting missions keeps them at that level. Either your or someone you played with accepted it too soon. --- Sticks and stones may break my bones but words will send me into a downward spiral of infinite despair.
