I have a problem when importing a spellcasting character from BG1 to BG2 (EE): the lvl 1 spell lists seem to get messed up. Druids gain Cause Light Wounds (and any Curse spells that were memorized at the time of importing will be changed to CLW), while Sunscorch gets deleted from the Shaman spellbook if it was picked. Expeditious Retreat was also deleted when I tried importing a Sorcerer.
Lvl 2+ spells are all present and work fine and none of this happens when creating a new character, only when importing.
