@Matt Creek,unfortunately due to the Coronavirus restrictions Chessington Buzz nor Theme Park Guide could ride Tomb Blaster today. Chessington Buzz said too me via Facebook that no external changes have taken place to Tomb Blaster. Of course this does not guarantee that Forbidden Tomb has returned in all but name. Obviously the Forbidden Tomb sign is still above the entrance so the canvas sign saying Tomb Blaster could be taken away at the last minute to expose the Forbidden Tomb one.
