when you haven't farmed for a while the Tools and XP hud disables automatically, not like its hidden and ones you start farming again it shows up, but the feature just disables itself and you have to turn it back on again in the settings
Edit: If this is the Session Hub Enabled setting than it shouldn't disable the feature but instead hide the hud ones you stop and starts up again when you start farming again
