Self's location tracker
Instead of using "Trigger when a specific situation is encountered" Trigger events to have triggers based on location, you can use a tracked item to manage this for you
Tracked item:-[edit]
Name: Location
Type: Text
Description: Describes my location if I am at a key point of interest
Visability: One of the AI visable options
Automatically update tracked item: Yes
Update instructions: Whenever I go to a new location, if it is a location on this list, set the value of this tracked item to that locations name.
For example, if I go to the hospital, set this tracked item to Hospital
List of locations Attic

Post office
If the location does not appear on this list, set my location to Not at point of interest
