Every time i meet a bandit in the digital version, I am forced to recharge a card. Once I recharge, I am given a new card. From what I understand, this is not how recharge works. You don't usually get a replacement card.
I just played through the digital RotR campaign myself (on PC).
I'm pretty sure what you describe is a scenario effect. I forget which scenario it is, but one forces you to draw a replacement every time you recharge a card.
