Weird pacer behaviour

Any one ridden with a pacer today and noticed weird behaviour?

I was riding with Bowie Brevet today when all of a sudden he dropped right off the pace going up the titans grove kom!

The group and myself slowed to 1.1/1.8 w/kg and still rode away from the B class pacer (3.3w/kg), I came to a stop at the top and waited for it but the time for Bowie was jumping all over the place, one time it said he was 32 secs behind then 45 secs and so on. I never lost any riders from the screen and other people in the group were putting messages in the chat asking what happened etc.

Anyone else had it?
