If you bothered to looked and pay attention to any of the other posts on the subject, there is a number of people that have characters locked in the walled off room that ARE able to get tokens still. There have been multiple posts where people are happy that they did not remove all their characters from the room and still have access to tokens/puzzles.
Someone else posted that the Dev's or GM's have to go in daily at server up to turn OFF the box, however, until this is done, the box is fair game and people are able to obtain tokens and do the puzzles.
