estanis, something's not right. Maybe something went wrong with the wallets during the upgrade, since you and I withdrew during the upgrade I think. It's been more than a whole day now, nothing showing up in the Block Explorer or my account. This is something on their end, I hope they fix it or refund us.
I hope so...
What I've seen in the poloniex trollbox is we are not the only ones with the problem.
It would be great if someone (from factom) could explain us why it is such a delay...
