Hyperactive vikings on my boat

Has anyone else seen the shakiness issue when sailing with other people? The boat is smooth and I am normal no matter if I'm steering or just sitting. But every other player is vibrating all over the place.

I've played since Valheim was first available on steam and never saw this issue before. My group just started a new world last month and everyone notices it.

Any fix or is it just a result of the engine updates?
