Hi Chris, hope all well. I wonder if you can please help? I'm prob a couple weeks away from wrapping up a big demo, yay. Using AC 1.85.1, and Unity 6.

So, I used and adapted the included Title Screen template for the title screen. I think it already had a 'BlockPauseMenuEventRunner' in the scene, or at least there is one there. The title screen menu works as intended when the game first boots up - going into eg LOAD or OPTIONS and then BACK returns the player to the title screen menu and not the pause menu.

However, while playing the game, and in the Pause menu, when the player selects QUIT from the pause menu it goes to another menu that asks player QUIT TO TITLE SCREEN? Yes or No.

If the player selects Yes, then the scene ends and I do a 'Scene: Switch' to the TitleScreen.

Now however, if the player goes to LOAD or OPTIONS and then BACK, both the Title menu AND the Pause menu show up.
However, none of the buttons on the Pause menu work /, while the button highlights work, clicking them does nothing.
If I try to lock the Pause Menu on the Title Screen's OnStart ActionList, then BACK doesn't work.
The Title menu still works though.

Any idea why this may be happening, please?

Almost as if the EventRunner (that blocks the pause menu and instead loads the title screen) is only running when the game first starts on the Title Screen, but not when I go back to the Title Screen scene.

Nope, the event runner is running and triggering the correct ActionList when I load the Title Screen later. Checked with a comment in the console.
