Yes, the signboard. You stop bumping into one object, then move in another direction to the next object and so on. It's a riddle. We'll add the path to the walkthrough soon.
Then the path is incredibly obscure. I tried mapping out all the paths in my head and found none that lead to the pickaxe.
Doesn't help that when she's on a specific tile, your path ignores her entirely.
Here's a video.

Thank you. I will still get back to you if the pop-up appears a third time, and will continue trying to screen capture it should ut do so.
