I try to update from 0.10 to 0.11 but the save games doesn't show up.
Android version.
With android devices, you have to manually copy/paste your old saves from your com.androidterrene folder in your storage to access them.
However, since a lot of android users don't know how to do this, the next update after v0.11, just has an option to jump to the latest content, so you won't need your old saves anymore
