i bought the season pass for borderlands 2 some time ago and got pirates booty and campaign carnage no problems. took a long break, go back a couple days ago to download sir hammerlock and dragon keep add ons but not allowing me to have them without paying. description on both says its part of season pass. and even on the previous season pass downloads, says i have them but no longer says they're free. tried redownloading season pass and still no luck. what am i missing?
