Issue : Spiral Bomb is unbuyable even though I don't have it.

How to replicate : Unsure, I've RBd. But  I may have also previewed the spell? Or my last char did have Spiral Bomb, so that could be it?

looking at your spelllist, i assume you have shadow dive. If so, that's why. I don't know what it is but the game considers it that you 'have' spiral bomb if you have shadow dive bought and so, cannot buy it.

Edit: It's also an intermediate so you need 20 more rpp to buy it but I assume you know that. Just putting it here in case.
