This issue is still happening from time to time as far as I can see and I think this issue cant be fixed permanently. As we all know Lightlord is managing his casino almost himself, Zodiac may help him but I dont think Zodiac is responsible for the hot wallet. Means that anytime the hot wallet is getting empty, Lightlord is the only one who can refill it. This can be a big issue if the hot wallet is empty and Lightlord is having no time due to some real life issues like his health long time ago.
The entire concept of having hot/cold wallets is to not hold too much of the funds in the hot wallets, as they're deemed more risky. Which means they may be running out of funds whenever there are more withdrawals than deposits, for whatever reasons. So it all boils down on whether the level of funds is properly monitored and whether site admins are fast to refill hot wallets if needed to.
Someone reported
here that Zodiac is/was active in the BitVest chat, if so, that's a bit comforting knowing the site has more than one active admin.
