Considering the fact that all the BTC is still untouched in their
multisig address, what are the chances that something actually happened to the owner and he was the only one with access to everything?
That would tie-in with the part when the owner told Hhampuz he had travelled but was returning and during his absence he did not allow anybody complete access to the Whirlwind server. Though it would still not be enough negate any negligence on his part as things currently stand, with the funds untouched after all this time it raises more questions about whether something really did happen to him.
I got an email back from whirlwind just now and it was as I suspected - something happened.
Basically, main people lost access due to travels while people still with access didn't have the right credentials to solve basic issues that caused withdraws to get stuck on the back-end. I've been assured that nothing has been lost and that all will be taken care of tomorrow meaning all currently pending withdraws will be processed and things return back to normal. It was an unfortunate situation is all!
I've asked my contact at whirlwind to reply in this thread whenever they can with further details, so from now until then/tomorrow night there is no need to panic even if I wouldn't recommend you to deposit until the backlog is cleared. Campaign participants will also be paid out as per usual tomorrow, regardless of if you've removed your signature or not.
