No confirmed fix yet. Players suggest: Perhaps the implementation of the change caused the bug?
Suggested fix (unconfirmed): Enter a new room with Lovelace in your party to force the gallery to register her final level. Do not discard the upgraded girl until you have entered this new room.
Suggested fix (unconfirmed): Equip your mods on the load-out screen before starting a game.
Suggested fix (unconfirmed): Queue another damage converter after Akiko to change her poison damage into another damage type with its own multiplier. Alternatively, pair poison damage with smoke and use laser, gauss, or jet modifications to manage range and projectiles.
Suggested fix (unconfirmed): Level up and unlock all items in the gallery, including crappy units, to reach 100% completion.
