Or we have to open lfm+ parameter, disable it and reenable it to make it work
Easy to reproduce; it happens everytime I start Wow.

Version 1.5.8

Multiple post on curseforge

Should be fixed with v1.6.0

Thank you for reporting. Working on rewriting on savedvars are handled.

This should now be fixed in version 1.6.6 and above.
