You can tell there is a hidden exit east by the map, and the text indicates that the wet footprints abruptly stop which also indicates a hidden exit... but there's nothing in the text guiding you on how to actually reveal the exit. Looking at the data I can see there is a hidden item (a stone), and when you look at that it becomes obvious what you need to do, but there is nothing in the room description that would prompt the player to look at the stone.
In my mud I intend to fix things like this and I was wondering if anyone knows of any other examples of this kind of thing (puzzles with no reasonable way for a player to know how to solve them).
Alternatively if I'm just being ignorant and there's a hint somewhere else telling a player to look for a stone when they get to the dead end that'd be good to know too.
