yeesh, we need a sticky post on working around the bugginess of the LTF. is it only doing this on webgl?
anyways, iirc the workaround is to visit each screen of the game, running the ltf each time - if it leads to an exit ignore it and go to the next screen, eventually you'll be on a screen where it can lead you to tiles. To make sure you visit all the screens, there's maps in one of the sticky posts for the event.
