You want to know something? I don't think Mozart's going to help at all.
So, what does the bold section below mean?
Attention: All adventurers and their companions on
the river passed by the water sprite are immediately
removed from the game! Put them back in the box!
I hope it just means that whatever space the sprite moves to bumps adventurers in that (new) spot.
But I fear there may be a "pathing" thing that could knock out adventurers between previous and new locations.
