Dedicated server spits out error message and has terrible performance over LAN

When running the Third Person template in Visual Studio with the commands of
“$(SolutionDir)$(SolutionName).uproject” Example_Map -server -log,

I get the following error spammed, with only 2 clients connected (one on PC, one via LAN).

What’s the cause of this, and could it be related to the terrible performance / teleporting around of the two characters relative to each other?
