How to repeat: Open settings menu, adjust the map overlay opacity slider, it works as expected, can see this if you make the changes with the map open with settings open, close settings, and opacity works as expect. Reopen settings and instantly the opacity settings revert to default.
Issue: After setting opacity and closing settings, if you open the settings window, you need to manually apply the opacity before closing settings, otherwise you have defaulted/reverted opacity, not expected behavior, not retaining settings on this particular adjustable.
Minor bug, but something to toss into a QoL patch sometime.
Thank you,
