overworld() resolves the world from under the stack, so a call from a
battle hook stacked a second battle over the live one -- on a loss its
afterBattle blacked out and warped with the outer battle still up.
newWild marks the species SEEN before it reports an empty party, so a
refused call still wrote the Pokedex; test the party before building it.
tonumber accepts 5.5, which Pokemon.new writes straight into the stat
calc and the exp curve.
