When would a dupe poof? I just made an Enigma(on Sunday) using a self found Ber and a traded Jah. I have no way of knowing if the Jah is a dupe or not, so every time I play I cross my fingers hoping I didn't waste the Ber. So my question is: If the Jah is a dupe what is a reasonable amount of time to be concerned about it disappearing? (rust storm aside) Thanks for any input, and I hope this isn't "against the rules."
