Riders darting all over the place during a workout

I took part in a Zwift workout (Amalgam) today that was an “event”.
I’ve done dozens of these, and I’ve enjoyed them all.
During this one, the riders around me were shifting all over the place, zig-zagging, going off the road etc. It was annoying & distracting to the point that at times I stopped looking at the screen.

Has anyone here had the same experience?

Thanks

Are you running the most recent version of Zwift?
