I kinda have this same-ish problem of other guides not showing up recently when I log in to play. The guide is repositioned to default and the guide tab I’m on (I have it set to show all 4 tabs) doesn’t show the last guide selected before the previous log out. When I log in nothing shows on the home page except version notes. In order to get the guide I want I have to search for it.
When this happens the gold minimap button has also disappeared and will not reappear until a guide is chosen. And I have purchased the whole Classic Guide.
