This issue is so typical of SE, it begs more questions than it answers.

Since the process can take up to FIVE DAYS and the locks are dynamic and so during that time the destination world may get locked, unlocked, locked, unlocked several times .. so what's the point of this check, it can be 'passed' one minute and then 'fail' the next.

Or, do you have to wait and not play (which means you're unable to play in time you've now paid for) only to find right at the last minute if the xfer has worked?

Kind of ill-though out, isn't is SE?
