I found a bug in version 1.7 in which I can't kill Tundra due to a script being missing. The last version I played, version 1.5, worked perfectly fine. Thank goodness you fixed it!
Can you be more specific? Does the game crash? What do you mean I fixed it? I tested it on my own and seems to work fine. If the problem is that you cannot deal damage to her, it's because you require an item to hurt her, and you need more than zero MP.
