It appears that the After going to Forest:
rule is understood by the compiler as another After going to Forest Path:
rule. As there is no room called “Forest”, it is assumed to be a reference to the Forest Path.
So when continue the action
lines are added and the player goes south from Outside House to the Forest Path, both the After going to Forest Path:
and the After going to Forest:
rules are run, one after the other. So the player is first moved to F by the first rule, and then to the Hospital Room by the second.
