Speak to hope customer service – usually very helpful with this issue
Most recently happened twice with aluminium body on my road wheels, replaced foc. Third time they gave me a steel body foc.
Also happened on all my pro II Mtb wheels even with sram pg990 or XT spider style cassettes.
Filing does not address issue because once the splines are worn the cassette becomes a loose fit which can cause creaking and shifting “noise” under power even with locking at 40nm. Problem only gets worse with time..
Filing will allow the cassette to be refitted easily though 😉
