Getting an error message when I continue off a save but it appears to cause no issues

So when I hit continue, I get this error message:

But it’s not causing any problems in the game, and I’m deleting sprites when I’m done with them so I’m not sure what could be causing it. Any help on where to look for solutions would be helpful.

You need to remove the variable also iirc. I used to get this error too.

Thank you! Do you mean using a var, setting the value of the variable to something arbitrary when you’re done, or is there a way to delete the variable that I don’t know about?
