MultiplayerSynchronizer and players sharing collider layer causes undesirable spawn location

Tested versions

Reproduced in Godot 4.2.1

System information

Windows 11 - Godot 4.2.1

Issue description

When setting up a simple local network fps game, I discovered that if players share the same collider layer, regardless of where the first player is currently when the second player joins, the new player will appear in either a seemingly random location or on top of the last-player-to-join's head.

I believe this is due to the very first frame on the joining clients end where both players occupy the same 0, 0, 0 location before the MultiplayerSynchronizer has had a chance to position the players retrospectively.

Steps to reproduce

Create a simple network capible game using a MultiplayerSpawner node, a simple flat plane, and a player scene containing:

• simple pill body
• collider set to layer 1
• MultiplayerSynchronizer that is syncing the player position.

Minimal reproduction project (MRP)

You can use https://github.com/devloglogan/MultiplayerFPSTutorial project as an example, but you need to set the player collider layer to 1 so that every player shares the same collider layer.

Are there any good work arounds for this?

Are there any good work arounds for this?

In my case, what I did was to simply remove collisions with players. This worked out okay for me because I replaced it with a little bit of code to give the players a soft push away from each other instead of it being rigid.

@LexGear Can you share any code on your work around? I have the same issue with my project. Turning off the collision mask on my player "fixes" as you mentioned but now I don't have collisions between players.
