I think there are two climbs, Norton and today on the Coullole that overlap the Cauberg portal climb. While they work fine on Zwift itself, on Strava riders get credit for the Cauberg without ever riding it. Both climbs are not as steep as the Cauberg and therefore, riders are taking faster times credited for the Cauberg. It was bound to happen with 49 climbs that this issue could arise.
Is this the death of the Cauberg? (I trained so hard for this climb, two minutes of all out effort)
Wouldn’t a little kink in the road for the Coullole fix this issue?
