WARNING: please back up your important worlds to Dropbox before updating to 2.4!
2.4 update released on Google Play earlier today.
The update appears to be wiping the existing worlds – the list of worlds is blank after the update. This is totally unexpected, the game itself is not wiping the data (and remains fully compatible with old worlds all the way down to 1.0 alpha, from 2011).
It seems it is the installation process from Google Play that is wiping the data. Unfortunately, this is beyond my control. It’s Android and Google Play Store infrastructure which perform the installations/updates. For some reason at the moment unknown to me, they either uninstall the old version before installing the new one, or change the location of the data directory. The new version of the game sees a blank slate after the update.
Sadly, there is not much I can do about it right now. Again, please backup your worlds before updating.
