I tried a small withdrawal from poloniex, but all it's showing is "COMPLETE: ERROR". There is no transaction ID shown, and my wallet on poloniex shows it hasn't had any coins withdrawn from it.

This must be poloniex's wallet QPVknSmwDryB98Hh8xB7E6U75dGFYwNkJ4 because my coins from my last poloniex deposit were swept into it.

It contains over two billion coins, and forged most blocks until block 162891 on 2015-12-26 16:23:16 utc. After that it hasn't forged a block. Is poloniex's wallet resyncing?
