How come whenever I transfer my modded saves from xbox 360 to xbox one on borderlands 2, the characters are all level 72 still, they have their guns and inventory, including bank inventory, but I cannot buy ammo? If i buy or pick any up, it instantly disappears. And now if i can obtain ammo, I cannot buy any eridium upgrades, as it shows they have all been purchased and I cannot obtain more than the standard amount of ammo. Can someone please answer this? The saves work completely on the 360 with ammo amounts and all, but as soon as they get transferred they go to shit. Please help me with an answer and solution... Thanks

And dont tell me to play the game anymore, I want endgame content as I have made it through probably 20 or more playthroughs.
