No owning connection for actor

This may not be the sole cause of the warning, but typically I see this warning when I do the following:

  1. Spawn a pawn
  2. Replicate properties from client to server in BeginPlay or Tick (or some other early/recurring function)
  3. Pawn possessed

I’m usually able to resolve it by preventing any of those RPCs from executing by checking if IsLocallyControlled() is true.

I hope that helps!
