If you're playing the game in the browser, please refresh the browser - the new fix I made is that the "light fishing pole" option will always show up regardless of whether or not you have the pole, and I'm pretty sure of that. So if you're still not seeing that, it means it's an older version without the fix yet.
edit: will try to reupload a new version that will overwrite stuff, please allow half an hour from time of this posting to try again!
edit2: should be up now!
