Normally, I would be using reflection and AccessTools to create a new instance of ServerSettings and set the value of PhotonNetwork.PhotonServerSettings,
but since it was difficult and confusing with IL2CPP, I ended up just using explicit references.. every targeted game build *should* have these types anyway.
Now I'm wondering if the patch runs faster when using explicit references rather than reflection
