I just want people to know that there may be bugs like this on this site and support won't support you.
meaning this is only a warning ? because after posting this you did not come back here and just let people talk about the case.
is there any chance to update us if Stake already reaches you out?
Just like stated early, this is a pour case of bug and slow networks connection that has resulted in this kind of loss, but on the other hand, some casino already has this covered in their T&c stating their sole right to deny players their cash out request without any obligation.
While some may think that this is unfair we must remember that casinos deal with tens of thousands of customers, and each one of them has a different configuration of hardware and software, so it is impossible for them to check that every single feature of their casino will work as intended all the time, so things like this can happen once in a while.
And if casinos did not had that kind of policy then some cheaters may try to use such delays to claim undeserved profits, so casinos have no option but to protect themselves in this way.
