I looted a couple 100/250 NX cards after killing HH and when I went into cash shop my NX remained at 0. It got rid of the NX cards from my inventory though. Didn't have this problem before until now and I don't know if it was a one time thing or will stay that way. Just wanted to let people know just in case it's happening to everyone and not just me.
It happened again on my other account that I have not voted on, JoesHero, if that could be investigated too. Thank you.
