Battery 4.3.0 (RO (or R0?)), full license.
Why? I can save single cell to this location. The location is just a normal writable folder.
(The other thing is that few Batteries and Kontakts increased my reaper project file to 180 MB; probably because of moving project from Win to Mac and resolving the missing files dialogs. That's why I need to save the presets/kits/etc and load them once more. Still looks like a bug in both.)
