It looks like the alphabetical order is something the engine is doing now? My order keeps changing inside Project Settings -> Input to alphabetical on its own. I’m putting the bindings in the default binds array alphabetically and trying it again.
It still doesn’t work correctly in the editor with two multiplayer players under the same process. I’m building the game again and I will try it as a stand alone to see if the problem fixes itself. I’ll let you all know what happened.
