The client crashes whenever I attempt to sell the last TT card to the aforementioned NPC. It has happened twice so far on different times.
I am not sure if I get the MGP from selling the cards transferred to my character safely, because both times the client just freezes and crashes. It is also always the very last card on the list.

If it is from importance - both cards were epic cards that sell for 200 MGP each. One was Minfilia and one was Ramuh.

I've had this problem three times now. One just happened right now. It doesn't always happen, though. I'm curious to know if you are on PS4, since that appears to be version of the game that has this bug (although it may affect other platforms, but I've yet to see any indication of that).
