We have just released a minor update on Google Play. This is version 2.2.009. It is not a required update, but you can update if you wish.
There are no extra features to this update (so don’t worry Steam/iOS users), it mainly includes bug fixes specific to Android and removes some unnecessary permissions that the app was requiring. Any bug fixes relating to gameplay (such as spells) will be fixed in the next major update alongside the Steam/iOS release.
