Scott,
I wrote a simple example, see below.
And run it with eval 4.5 + daily build from around 6/6
And run it with full version with WpfDesktopEditionFull5.0.42.0DllPackage from today
On each version I grab the marker originally in Poland to Russia, then it is supposed return to Poland, then I grab it from Poland and move it to Spain
In 4.5 It disappears from each of those places after each drag and re-appears in Poland
In 5.0 it correctly reappears in Poland but each time one stays in Russia and Spain, basically the marker gets copied. But when you pan the map those two copies do not move with the map, as if they are on a different overlay
I attached screenshots
Take care
