Every time you rotate the screen, the cached list of skills etc. gets thrown away & reloaded, which kind of blows the point of caching it. You may need to make the configuration & repository objects (and everything they contain) Parcelable & store them in onSaveInstanceState()/onRestoreInstanceState().
Related to this, the currently-selected skill doesn't get saved across onDestroy()/onCreate(), probably because you're dynamically building the list of skill-name UI components. (But aren't you also doing something similar for the adventurer name? That gets persisted correctly.)
