DraStic

Phone - Moto G (2013 no LTE)
CPU - 1.2GHz quad-core Snapdragon 400
Drastic Version - 2.3.0.2a
Android OS - 5.0.2

Roms are stored in my Download folder. I extract them with ES File Explorer and play them on Drastic. After quitting the Roms are not found /anywhere/ on my device.

Finally maybe nore then a simple one line about the problem. Like where the roms are stored on your device. Do the roms get completely deleted, or is it only the savefiles? Things of this nature can only be of use.

Have you tried anything else, for example putting the roms in another folder? I know it shouldn't be deleting roms in the first place, however I just pulled out my old 2013 Moto G and updated to the latest version of DraStic and my roms (located in my "Roms" folder) were still there after running them.
