TC is confused by what TVHM is I think. TVHM is essentially New Game+, so any lower level character will have to start in Normal mode, and your higher level character can switch between normal and TVHM. --- PSN ID: CrimsonSamuraiX
TVHM is simply NG+ with your character. It doesn't affect anyone but the character in TVHM, unless you're the host in multiplayer.
You can switch to PT1 any time you load up the character though, as long you actually switch them in on the title screen. You won't get the option if you simply select continue. --- ~Mirror, mirror, on my floor, am I the prettiest at the store?
