GT New Horizons errors in server log are they game breakers?

[Crazz2323]

I downloaded the GT New Horizons server and client pack, all seems fine and client can log in fine but in the server logs, I noticed a lot of errors. I know this is supposed to be a complete pack so I assume these errors are not game breakers and are acceptable?
