This crash happened when I have buttons in a character select screen
Can you screen shot the events with the button is clicked or button is pressed condition?
Unfortunately I have already refactored my event sheet to have no buttons a few days ago. All I know is that I used the option to make a button from scratch. And the game would Insta-crash on startup, I have already tried to debug this myself, and it only went away when I got rid of the buttons altogether.
