Locus can't load maps in external sdcard

[1bertoc]

Hi! I'm on Samsung Galaxy Note 2 and Cyanogen 12.1 (Android 5.1.1) latest nightly. I have a 128Gb external sdcard formatted in FAT32. In the Locus folder a have another folder called maps where I put more two folders one named AERIAL and the other named RASTER both of them have lots of folders with maps maps created by MOBAC or Orux (xml and db files).
When trying to add those folders Locus display a message saying problem with "name of the folder" and doesn't add the map(s). If I put the maps in the internal storage everything works without problem but I have a lot of maps so the internal storage is not a solution. Any clue? How can I solve this problem?

Thanks.
