In this topic (https://forum.locusmap.eu/index.php?msg=77233) I have already reported problems with the new My Lib database when icons assigned to points or folders are missing.
But there is another problem that affects Locus in general: The created audio coaches can be named individually and you can assign any icons to them.
If you delete or rename the corresponding icon zip folder(s) and then open the audio coach menu, Locus regularly crashes.
You then have no chance of replacing the icons that cannot be found with others. The only way out is to restore the removed/renamed zip folders (you should have backed them up beforehand), only then can you open the menu again and change the icons.
Thanks, will be fixed in the next app (Beta) version.
