PREVENT character movement replication

I am currently working on my own custom character movement replication which does not involve the generic “replicate movement” setting:


The issue is that in spite of unchecking the box, changing the location of this actor on the server causes the movement to replicate to the client, which I do not want. I’ve scanned the code to see if there are any multicast RPCs setting the location of the character but there are not. I am also not using the character movement component to perform movements on this character. Any ideas what could cause this behaviour?
