Hello, sorry for your issue. If you're playing on Android, and don't use the cloud save system, you have to follow the instructions displayed when you download an update:
Installation instructions
Android (how to keep your save file)
- About the Android version, unfortunately, the fix we had made to make sure the update would work isn't working for everybody.
- So to make sure you keep you save file, you'll have to manually backup it.
- To do that, you'll have to use a file explorer, and find your saves in /Android/data/com.GrizzlyGamer.RMAWhellcum
- Copy everything that's in there and paste it somewhere else, In your download folder for exemple.
- Uninstall the game, and install the update.
- Now you can copy all the files you backuped earlier, and copy them in the save folder: /Android/data/com.GrizzlyGamer.RMAWhellcum
If you haven't, then I'm sorry but there is nothing we can do. We implemented the cloud save in january to prevent that kind of situation.
