Has anyone else experienced an issue with local variables being stripped out when declaring a champion email? This has happened for all of our modules, and you're unable to update the variables in the new champion email which means having to essentially rebuild the email.
Global Variables seem to be unaffected.
I've never seen this before (and use both champ/challenger + local variables heavily).
I'd create a ticket with support - this might be one they're better positioned to help you with than community.
