Sram Cassette Issue

I have a Planet X London Road with 1x11 Sram Rival groupset.

The bike has developed a persistent rattle and I have tracked it down to the cassette (PG-1130 11-42T) where the innermost 3 rings are loose and rattling. The problem started out of the blue - nothing on the bike was changed, the cassette was not removed, no crash damage (either minor or major) - so I'm slightly confused by what caused it.

I have taken off the cassette, remounted it and tightened it. This stops the noise for about 5 minutes and then it starts up again.

What's the likely cause? I wondered about a lost spacer maybe?

Alternatively do I just suck up the cost of a new cassette?

    Try sticking a 2.5mm or whatever size the really thin ones are behind it all and doing it all up to 40Nm and see what happens.

    The camera down the willy isn't anything like as bad as it sounds.
