Locus compleately removed personal map folder
All offline maps are lost... never mind, I can restore them from PC.
Here is how to reproduce it. (DO NOT TRY!). Confirmed on Pro 3.8.2 and Beta 22.214.171.124
1. Map manager > Download > select any area > Download button
2. Now, select "Compressed map (TAR)" then tap CALCULATE button.
3. Locus asks a question "Map of this name exist! Overwrite?". If you answer "YES", Locus/map folder is removed.
