Minimap / Overlay is reset to undiscoverd upon map leave/reenter

Hi

evereytime i have to reenter a map, the minimap the overlay
loose the already discovered / unveiled areas and i have
to rediscover the area again for it to be revealed again
in the minimap / Overlay.

Problem exists for me since 05 April

In thge Screenshot you can see the map reentry in the middle of
a map and that the areas laeding to that point are not shown
anymore in the overlay
