In the rule Effects, change “add it as a Hazard to the Location of the applying Pathfinder” and “Add the Discovery as a Hazard to the Location of the applying Pathfinder” to “add it as a Hazard to any Location where it is present” and “Add the Discovery as a Hazard to any Location where it is present”, respectively.

Extend all Hazards to every Location where their relevant Discoveries are present.

Add the following to the end of the rule Effects:

General Discoveries can never produce Hazards; if applying an effect on a General Discovery would cause a Hazard to be created, instead no Hazard is created.

If a General DIscovery is a Hazard in any Location, remove it.
