I have a button setup to browser -> go back action. When running the game I realized this did not work with a console error that window.back() function did not exist in main.js file in the c3 scripts folder. I realized this function probably needs to be window.history.back() instead. Making that change in the main.js file seems to work. Thought I'd share it with the community.
