"An Invisibility Charm has been put upon new stadium. Please collect Re-Visibility Spectacles from ticket office or you will not be able to find the pitch."
Some match venues in the Quidditch League require invisibility charms due to suspicious Muggles. Spectators are reminded to collect their Re-Visibility Spectacles (Re-Visibility glasses) from the ticket office to be able to find the pitch.
In the Falcons and Pride of Portree match at Exmoor Stadium, fans and spectators were angered at the faulty Re-Visibility Spectacles (Re-Visibility glasses), which caused them to not be able to find their seats or watch the match.
