Game Stuck On Downloading

Whether it's an app or Android update, sometimes the game will refuse to progress after allegedly downloading. The go-to fix is:

Backup AuthKey: /SD/Android/data/jp.co.lifewonders.housamo/files/Data/AuthKey
Remove /SD/Android/data/jp.co.lifewonders.housamo/files/ (or every other folder except /SD/Android/data/jp.co.lifewonders.housamo/files/Data/)
If you're keeping /SD/Android/data/jp.co.lifewonders.housamo/files/Data/, remove /SD/Android/data/jp.co.lifewonders.housamo/files/Data/MasterDataVersions
Remove /SD/Android/data/jp.co.lifewonders.housamo/files/
Remove /SD/Android/data/jp.co.lifewonders.housamo/cache


Relaunch the app, or copy AuthKey to /SD/Android/data/jp.co.lifewonders.housamo/files/Data/AuthKey

You may be able to get away with removing the cache and MasterDataVersions, but an almost clean slate will do.

Malformed Cache

 
 
There's some odd behavior when running Housamo on Android 8.0 the game fails to initialize properly from a clean slate. From what's given, asset appear to cache when they can't. More information on (the theoretically) why here.
The steps to restore the game back to a playable state is also as followed:

Backup /SD/Android/data/jp.co.lifewonders.housamo/files/Data/
Delete /SD/Android/data/jp.co.lifewonders.housamo/files/Data/MasterDataVersions
Delete /SD/Android/data/jp.co.lifewonders.housamo/
Start the app, and let it properly initialize (this will take some time)
Close the app after you reach the title screen
Copy your backup of /SD/Android/data/jp.co.lifewonders.housamo/files/Data/
