What's this? "RakNet detected a missing replica"

[Desblat]

The mod adds new mob. Then spawns it periodically, then deletes mob and spawns it again...

 

 From a log.txt, got this trying to connect to the modded server. Also world do not load at all on client while host is fine. No crash or error screen just this:

 

RakNet detected a missing replica (548)
RakNet detected a missing replica (164988)
RakNet detected a missing replica (77902)
RakNet detected a missing replica (196834)
RakNet detected a missing replica (183344)

What's this? Why does this appear?

i just got this error too. Did you ever find a way to fix it?

@Desblat, it appears even when you have no mods installed/enabled. I think it's them working on it and trying to fix or add things to the game.

Missing replicas.

 

That means there are things in the host that doesn't have a replica for the client to use, like any component you may mistakenly put before the TheWorld.ismastersim if. So it can appear if you have no mods at all, but join a server with mods with incorrect code.
