Might well be.
I can't imagine the scenario where two reprints are dished out on top of what would be, I'm guessing, an original smartcard activation of the ST.
If it's indeed the case, at least one of them should have been cancelled (and the smartcard shouldn't have worked either)
There's a failing at some point by the club whether it's either the duplication of a ticket printed and not knowing or letting two people in to the ground by some means.
I got 2 reprints the other day for psv..
Long story but season card is away to ibiza for a week....went into ticket office got a reprint took it home for sons friend to pick up b4 match..
He forgot to pick it up..he then went to ticket office before match and got another reprint with the email I sent him with purchase details on it.
So multiple reprints of one ticket
