I updated the code used in the linked example to allow it to work with the most recent version of PlayerModule and all its components. I want the camera to behave this way to prevent players from re-adjusting their cameras while standing, driving, or riding a vehicle.

I put the module from my test place into my main game and the custom code appears to not work at all in the game.
How it’s supposed to work in the test place and in a fresh baseplate.
How it works in the main game/some other places.
The Module is placed under the correct location.

This behavior is pretty inconsistent as it works correctly in some published/local file places but it doesn’t in other places.
I have tried using the older PlayerModule that’s in the linked post but that also appears to have the same inconsistency.
