I've seen the same happening in other casinos that they've announced their closure and they've give a notice for everyone to withdraw. But, there were still some users that left unaware of it because they're no longer active on that casino for a long time. And they've only checked it a few times and by checking it, they've missed the given period of withdrawal.
Most common thing that do happen and later complaints and issues would be raised on that they haven't able to withdraw their funds even if they had given ample time to do so.
Sometimes it isn't really just bad to make out some readings even if you are just playing then you should be sensible on various informations circling around so that you wouldn't
really get blinded specially into these kind of scenario or conditions on which you might be ending up on locking up funds.
