Can I ask my android version recently encountered a bug where I can't open the game anymore no matter what so I've been thinking of redownloading the game when the update comes out but can I just download the update directly? Or do I have to delete my current ver and then transfer my saves onto the updated ver because updating the game might not fix the issue
If you play on Android, there are update instructions on Wiki FAQ page and more info in Discord FAQ channel.
On Android you have to store the save files before starting the update, and copy them back afterwards.
You might try the same copying of save files and install the same version you now have, that might fix the issue. If it does not, it may be upgrading to new version won’t fix it either.
