Hello,
referring to r28169,
I noted new addition, when radar detected ufo, comes up with an "icon" of detected ufo. It feels similiar to a tab.
As usual, I saved, launched siletto to shoot that ufo down. This one, Siletto successfully shot over sea, the icon remains on the geoscape screen.
I reopened my save and let ufo pass, just to see what happen when flys out or radar range, the icon disappears.
So must be a minor bug... Let me know if you need any attachments (naturally in SVN bug tracking).
