So I'm not sure if this is a bug or not, but anyway.
The way my game is set up is that the first layout of the game is a just an empty layout, with two actions on the sheet:
On start of layout > load game from slot "xxx".
And If load failed > Go to layout "Menu".
At the start of each level (each level is a separate layout using the same event sheet) I save the game to slot "xxx".
The first Action in the event sheet is, On load complete > Go to layout "Menu".
This works as intended, and I can go to my level select menu and choose level etc, however, now any action that is to go to another layout (be it a specific one, go to next, etc) just doesn't work. The game freezes, and everything in the inspector disappears to shoing any layout information, or any objects anymore.
If I start the game from the beginning with an empty save slot, everything works, until I quit the game, and start it up again.
