I’ve read a similar post regarding this issue but let me explain my predicament.
I played Borderlands 2 on ps3 unpatched, no DLC’s whatsoever finished it got to TVHM finished it and then I was done.
After that I bought the Ps3 add-on packs which came with Torgues DLC and Captain Scarlet’s Pirate Booty and an update. I installed everything off of the Disc then finished the DLC. not that I have never connected to an internet connection at this point so no online updates or Hotfixes.
I then connected to PSN and downloaded an update which was around 600 Mb. Once i launched the game the option to continue in UVHM popped up. I was still level 50 and didnt get any XP whatsoever though I was playing UVHM.
Do i have to purchase each Upgrade pack off PSN to increase the level cap? Was it supposed to increase automatically after that update? Please get back to me on this issue, thanks!
