TDZ Stage 4 Longer Ride - “Missed your calling as a pro”

Did the TDZ Stage 4 longer ride today

Some 3 km before the finish, I suddenly got the “Missed your calling as a pro” message, even though I was riding in Z2 and can’t find any evidence in the FIT-file that the Tacx Neo was somehow misbehaving. Never had this message before and was certainly not doing anything abnormal.

I did get the mail I completed the stage, but the stage is not ticked off in Zwift and I’m not in the result on ZP.

Anyone have any idea what could have happened? Not important for this ride, but don’t want something like this happening in ZRL or the WTRL TTT …
