I found a path that can softlock the player (if they don't manually type "undo" to escape it and go down a different path).
On the Oscar path where he takes you into a forest and you run away from him, investigating the patch of grass leads to a "scene" with just the text "You can see an UnawareCVWolf." In the scene, "UnawareCVWolf" is an object that has the "Look at" and "Take" actions associated with it, but neither action has any functional behavior associated with it (the responses are "Nothing out of the ordinary." and "You can't take it.", respectively).
