As suggested [*], I create this as a separate new topic.
The following problem occurs when using the live geocache map of the geocaching4locus plugin. When I zoom in on a map, on the location of a "corrected coordinate" (the location of a solved mystery geocache, which was entered on geocaching.com), the waypoint icon on the map disappears when the "original coordinate" (the geocache location before it was corrected) moves out of bounds of the current map on the current zoom level.
This behavior makes sense, since the live map only loads and displays geocaches that are visible on the current map view. However, a corrected coordinate may be 2 miles away from the original location. The caches are loaded according to their original location, and thus the corrected location is not shown if the original would not be shown.
A possible solution could be to either load all geocaches that are up to 2 miles out of bounds of the current map (that is the maximum distance that GC.com allows between the bogus location and the actual geocache), or to cache loaded points, such that a corrected location should have once been loaded and displayed on the map, and stay on the map as long as locus pro is running.
I would think that the latter is most practical to implement. Just have a buffer for loaded points on the live map.
My current workaround is to store every solved mystery locally before I start hunting it.
