The hash file is only supposed to contain 1-2 lines. It is used to verify the integrity of the main file. Your data is stored in users.xml

Since you have root you can try making a backup of your data via Titanium Backup and then uninstall and reinstall the game. Ideally your progress will get restored automatically when you sign in with your Google play account but if it doesn't then you can use the copy you made with Titanium Backup. '''Backups made with Titanium Backup will not work if your data is corrupted. Proceed at your own risk! ''' This one is a long shot but you can try navigating to the root directory of your device and from there data/data/com.nekki.shadowfight/files. If there is a file called zone_2.dz, delete it. Then try reopening the game and see if it launches properly.
