If you can, backup your data, uninstall the game and reinstall. After that restore the data. This might fix the problem temporarily. Don't do it if you can't backup yourself as Nekki's cloud storage is botched and may not work.

There is sadly no permanent solution. The problem was introduced as the game got updated and only updates can fix it.
