I'm using the new STEAM trainer for fun and made my lvl 10 sniper to lvl 50 by using the trainer but my character doesn't gain any more exp at lvl 50 even by killing lvl 40+ mobs. Was just wondering why? I have all DLC's by the way so my level cap should be up.

When using the trainer, the game has to massively catch up on XP to get to the next level...

E.g. If you were to level up from 1 to 5 using the trainer, then the game has to get all the XP for levels 1,2,3,4 together.

Also I can't remember there is also the chance that level 50 is the cap?
