unfortunately not my friend, i wish my solution was because of something silly like replication being turned off, but i think it’s a lot more of a ■■■■■ than that.
I have spawned the players in using their PlayerCharacterParent actor, which has all the same code, but the default unreal mannequin character, and it all works perfectly fine, so i believe the issue is with the custom character mesh/physics… even though they work perfectly fine in singleplayer.
Thanks for the comment though, i do appreciate it.
