Buggy problem only on Client

Server behaviour

The left buggy is baked into the map, while the one on the right is spawned via GetWorld()->SpawnActor. Both work perfectly fine on the server, but only the right one has major problems on the client.

Client behaviour

The left buggy is still fine but the right one appears to have it’s wheels lifted ~6" off of the ground and shakes violently during gameplay.

Does anyone know what I can do about this?

Hey man, i know its been 5 years. I would guess that you are accidentally replicating something you shouldnt be replicating on your 2nd buggy. I had a similar issue where i was replicating the capsule, mesh and movement of my client players and the same thing happened. Super shaky and unstable. But if you dont replicate those things it will stop the wild shaking
