These withdraw issues are very worrisome considering they admitted to a server compromise, "wallets not compromised" according to hashnest, not too long ago and asked everyone to update their passwords.
History shows, that it is not unusual for platforms that had wallets compromised try to buy some time to remedy the sitiuation and replenish wallets.
I'm not saying this is what hashnest is doing but the pattern here is eerily similar to hacks in the past.
