UnwashedMass, if you still see the input bug after the update, try restarting. That is, typing "restart" in the game, not force-quitting.
A fire was lit under me! Hilariously, the first time I attempted to restart, it was auto-corrected to "restate". Then, with the mistake drilled in, I figured it would let me... and my second restart was corrected to "redraft".
OK, third time's the charm, restart achieved. Direction letters and i for inventory just return blank output in response without moving me from the starting location. But holding my nose and keying in "go e" from the starting location, direction initials seem to work everywhere else, only giving me the "I only understand you as far as wanting to n" error in places where N is not a valid direction ... which isn't the /most/ helpful error message for that particular mistake, but a big step up! (Correction: sometimes the single letters work, sometimes they don't, in some locations, according to no particularly perceivable rhyme or reason. Rigorous testing done here! At least i finally is returning useful output once there is something IN the inventory.)
So, hm, not perfect, but definitely /changed/.
