Curse's type_id was 0, which is bogus; this has been fixed by creating a real ????? type. Fourth-gen moves all had zero as a contest effect id, which was also bogus. Pokémon 494 and 495 were junk and have been scrapped entirely. pokemon_form_groups's description column was too short. pokedex's connect() now takes kwargs passed to sessionmaker(). A more major change: some tables, like pokemon, are self-referential and contain rows that refer to rows later in the table (for example, Pikachu evolves from Pichu, which has a higher id). At the moment such a row is loaded, the foreign key is thus bogus. I solved this by turning on autocommit and wrapping add() in a try block, then attempting to readd every failed row again after the rest of the table is finished. Slows the import down a bit, but makes it work perfectly with foreign key checks on.
