I hope its a glitch too and that they will eventually return everyone's coins, but I am skeptic. I was hit by the BTC/LTC balance deletion and have been patiently sending these support tickets and their responses so far were all automatic and not relating to anything I actually wrote about. Their last reply from a few days ago was actually encouraging - they requested I send all my balances and transactions. I didn't record that data and spent hours gathering it as best I could and sent it to them, only to got the same automatic response and issue closed again. Very frustrating.
