So, I know how to initiate a save script in-game. What I want to know is if there are any adverse effects to forcing a save in-game. Because I know that people not logged in to the site cannot save if they play the game in a browser. So if I force a save, will that have any adverse effects? Like, say, crash the game, produce an error, or hinder the game in any way on a browser?

To be honest, I don't know. Have you tried it?
