There were a number of problems at the 2019 World Masters. Several seeded players opted not to participate in the event in protest at a change to qualifying criteria. Other players who did attend found they were unregistered, having been unaware of a new rule which required them to register in advance online. Due to the confusion, officials announced that there would be a redraw, which included fake names, apparently so they could be substituted if more real players arrived. Players were also not informed of the event's prize money in advance.
