Wacky issue with multiplayer FPS tutorial

I have been following the multiplayer tutorial from quill18creates https://www.youtube.com/watch?v=AIgwZK151-A

After completing part 8 of the tut, my game that was working perfectly broke, and quill doesn't go into the issue at all. What happens is that when I launch the game, I enter the room successfully, but i cannot see other players in the world. If I look at the scene, the other player is there, but the game moves the player across the map, far away from where it should be. There is no code other than the controls that should transform the position of the character... I have no clue what could be causing this.

Does anyone have any idea what could possibly be happening here? Thanks.
