I have also a problem with kmz files which I import in locus. This problem may be related to this topic.
I have a large kmz file with some icons which are linked to POIs in the kml file. Some icons are not shown or a wrong icon is shown in the map.
I have shrinked the kml file to a small list of POIs and have seen this problem yesterday. Then I have changed some icons several times and now when I am back to the original kml file I do not see the problem anymore.
At the moment I am very confused because I am not able to reproduce this problem.
