Base map fails to update in Spectrum Spatial Analyst

Issue

Volatile data such as augmentations to base map data may fail to persist in some circumstances.

Cause

Volatile data has an intimate relationship with the cache settings and is therefore sensitive to how it is initially marked up in both the connection settings and data source property pages.

Resolution

UPDATED: December 12, 2018
If using volatile data then the initial connection to the data source must specify that the data is both 'live' and 'cached'.

Additionally the property page for the relevant data source must also have the checkbox ticked to indicate 'volatility' as shown below.
