Any blueprint with replication options such as PlayerController or Character has the Replication category and “Only Relevant to Owner”.
The tooltip says:
“If ture, this actor is only relevant to its owner. If this flag is changed during play, all non-owner channels would need to be explicitly closed.”
ture = true
It’s not an issue, but I remember seeing this months ago and shrugged, but just in case no one’s mentioned it
