Attach Actor to Socket replication

Replication not consistent some clients see changes others do not or see different challenges.

Simple call Controller to Character → Custom SERVER Event → Custom MULTICAST Event.

I am not sure why every run the outcome is different.

Any debug advice or possible replication setup that will work properly.
I am trying to swap actors attach points.
Start Actor A attached to Socket A on Actor C and Actor B attached to Socket B on Actor C
Then swap Actor A to Socket B and Actor B to Socket A.

thanks

If you on the server attach A and B to C with AttachActorToComponent then it should replicate to the Clients if A and B are replicated. You should never use Multicast when changing the state of the game, only use that when adding temporary particle or sound effects etc.

Yea tried that only the server sees the change the player does not nor does the other clients
