If you change any property of an activity in a child scenario, that activity will no longer inherit any changes to that activity made in the parent scenario. Up to version 5.1.5 of NoiseMap, the 'root scenario' of an activity is not shown, so it is not easy to tell from where each particular activity is inheriting its properties.
We therefore advise users to check carefully whenever they change the properties of an activity which is the parent of other activities, to ensure that inheritance is occurring as expected.
