· | referencedGoals - A list of other Goal objects that this hint references. By default, when this hint is shown for the first time, each goal in this list is promoted from Undiscovered to Open. Sometimes, it's necessary to solve one puzzle before another can be solved. In these cases, some hints for the first puzzle (which depends on the second), especially the later, more specific hints, might need to refer to the other puzzle. This would make the player aware of the other puzzle even if they weren't already. In such cases, it's a good idea to make sure that we make hints for the other puzzle available immediately, since otherwise the player might be confused by the absence of hints about it.
