I'm filling up the hotwallet now and also we see that the fee increase worked fine and most withdrawals are accepted into the next block.
Besides one short PM two days ago w/ little information, I've received zero communication from Randian Hero or anyone from Satoshi Dice about being robbed for ~78 BTC. I hope this means they are busy conducting an internal investigation, but it's definitely starting to look bad on their end.
Yes, we are investigating this case.
