During my visit to Prague, I noticed, that Live map fails to show caches with warning
Warning! Too many geocaches in the visible area, not fetching them. Please zoom in to resolve.
Too many geocaches in visible area, informing user
Moving the map little bit to the north shows around 20 caches, but the log reports
GetGeocachesWithinBoundingBox() 50.2,14.4: success
Number of geocaches in memory: 36
GetGeocachesWithinBoundingBox() 50.1,14.3: success
Number of geocaches in memory: 271
GetGeocachesWithinBoundingBox() 50.1,14.4: success
Number of geocaches in memory: 633
GetGeocachesWithinBoundingBox() 50.2,14.3: success
Number of geocaches in memory: 713
Which looks like the map is picking up a big tiles from surrounding area (city center) and it is exceeding some internal limit. Therefore the map is basically unusable (I agree that Prague is probably the place with highest density of caches all around).
Would it be possible to check what can go wrong in these places, that the map is not pulling too many geocaches and that the map is usable in such places?
