Forcing client to "sync" position of BuildingBlock entities with the server?

As a part of my project to add moving robots to Rust, I've ended up using BuildingBlock entities as my construction "tile" of choice for different parts of the robots. To test this out, I've attached them to a chicken - and to my surprise, the blocks do move! The move, but the client only ever checks for their position once every few minutes. I assume there's an RCP call that tells the client to sync it up, but I've not found that one yet.

Any idea how to force the client to update the position of the building blocks?

 

Send network updates to the building block.

BuildingBlock.SendNetworkUpdateImmediate() I believe it is

 

I've tried doing that in FixedUpdate method, and unfortunately that did not update their location for the client. I've looked through the methods of the BuildingBlock and I'm not even sure that there is one, which is why I thought it may be an RCP call.
