5 Beginner Multiplayer Mistakes

This is a review of 5 beginner multiplayer mistakes that we all make when starting out. Most of these are authority problems but I do look at a typical RPC issue when developing in Host mode. The final point reviews how I think new developers should approach their multiplayer journey.

Main Topics
----------------------------------------------------------------------------------------------------------------
1. Where to set client authority?
https://github.com/godotengine/godot/...
2. Order of MultiplayerSynchronizers in scene
https://github.com/godotengine/godot/...

[Both of these issues have the same error]
on_replication_start: The MultiplayerSynchronizer at path "/SOME/PATH" is unable to process the pending spawn since it has no network ID. This might happen when changing the multiplayer authority during the "_ready" callback. Make sure to only change the authority of multiplayer synchronizers during "_enter_tree" or the "_spawn_custom" callback of their multiplayer spawner.

3. Set client authority on server
4. Use "call-local" for RPC calls when in Host mode

5. Start with a prototype or proof-of-concept
