Undefined in the editor

Squirrel Code

I am seeing random locations in my code with “undefined” printed in it in the editor. The “undefined” seems to be some overlay, as I cannot select it. Not sure if it affects my code or not (it compiles and runs). Anyone else seeing this?

I think the fix for this was to click the editor cog (top right) and ensure your tab size is selected?

Yep, thanks!
