I upgrade a 7.9.0 redundant gateway to 7.9.1-RC1,  
the system tag Gateway\Redundancy\IsActive is broken.  
When I browse in designer, I have : Gateway\Redundancy\IsActive\Null ???

Scan class driven by tag [System]Gateway\Redundancy\IsActive seem not working anymore ???  
This issue seem occur after the first gateway restart… 😮

The issue seems to be Expression Tag (or Driven scan class) with reference to a tag path like [System]…  
When you reference to [System]Gateway\Redundancy\IsActive in an expression tag, this tag ([System]Gateway\Redundancy\IsActive) is _broken_ in the designer, after a gateway restart !

This issue might be fixed in the recent production version of Ignition 7.9.1. Just saying it might be fixed.

Best,
