Zarillion I originally opened this issue against HandyNotes, but I'm opening it here as well now that I know the issue is actually in HereBeDragons. https://www.curseforge.com/wow/addons/handynotes/issues/123 In Shadowlands, the MINIMAP_UPDATE_ZOOM event is fired when the Minimap:SetZoom() function is called (either by addon code or the +,- buttons). Using the SetZoom() trick to see if you are indoors/outdoors by comparing which cvar changed now creates an infinite loop of event callbacks when GetCVar("minimapZoom") == GetCVar("minimapInsideZoom"). Some other method will need to be devised to determine if we are are indoors or outdoors when the cvars match.
