Sticky pace partner drop bonus

Not complaining but… :wink:

Has anyone else seen this phenomenon? I got overtaken by the cat-A pace partner group when on a normal ride so I thought I’d hang along for a while. Suddenly the multiplier progress bar vanished even if I was just a few meters from the pace partner. Soon, the group took a different route at an intersection and I didn’t think more of it but I noticed that the pace-bonus blinked on my drop and did so for the entire remainder of the ride.
