I have honestly no idea. There's no way it could've been loose as I never touch it usually, and I handle my 3ds with great care. I can come up with reasons but its all speculation. Maybe its an inherent problem with the 3ds in trying to read 16/32 GB microsd's. Maybe it was a partitioning problem. Maybe it had to do with me putting all my downloadables into carpets. Who knows? Research I've made led to no conclusive answers... but I do know I'm not the only one this has happened to.
It seems to be working fine now... after I redownloaded everything back.
...how did that even happen? I don't see how that could have disappeared just like that. Was the 3DS's reader... loose? Like, did it sometimes not detect your card all of a sudden eve though it's in?
Oh you bet. First thing I did in fact.... there was nothing. It seems the only solution was to have the foresight that something like this woukd happen and preemptively have a copy of its contents on my pc ready just in case... which I didn't have.
I'm not that sure about how to value it either. Coin-wise, 3,000 - 5,000 coins would be nice for a holo. Houndour is not a game-changer though imo, I'd probably trade it for two candies. Whatever feels good for the both of you should be fine, really.
So pengy redirected me to you. I was going to give him a holo rare Houndour card I just got from the Casino, but I don't really have much of an interest at TCG and I don't know how much candy I should ask him for it. In your opinion, how much candy can I charge him for the card? :S
