Maybe usefull to report this:
GB Handling of very amounts of coins.
When having very small amounts of coins, GB is unable to sell them (because of the minimum BTC required?) which effectively locks the pair.
workaround: manually buy extra altcoins and sell them.
See log extracts below, during the buy only 0.59114983 coins were filled of the order of 660.
Which resulted in the message of: we have altcoins: 0
