Glitched achievement?

[Ninjav Inny]

So, I've already finished the game with both Yunica and Hugo, and now I'm playing on easy with Toal. However, I just got past Velagunder and I didn't get the achievement fr beating him with all the characters. Did this happen with someone else? Is there something more I have to do to get this achiev?

Nope just beat it with all three
