Critical Research Failure: "Blanche Neige" is the French name for Snow White, but the machine's design is based off of the pumpkin carriage from Cinderella; the mechanical designer admitted on Twitter he got the two fairy tales mixed up. Reportedly, Houko Kuwashima (Cliana Rimskaya's voice actress) even asked "If it's named for Snow White, why is it orange?"
Aside from the problems with the Game-Breaking Bug, any attacks dealt towards Protodeviln units not coming from Fire Bomber do half damage. Adding to that, Fire Bomber members burn through "Song Energy" very quickly and there's no way to recover that aside from the standard 5 EN per turn (this is fixed in Super Robot Wars Alpha 3, but with a different mechanic).
On the flip side, Destiny has the "reduce EN cost by X percent" equippable parts, which work on the Sound Force. Judicious use of "Armor Breakers" attacks and "Support Attacks" (but not the "Direct Attack" Spirit Command) will negate the Protodeviln's effects.
Unlike most SRWs, if an attack is strong enough that it'll become a deathblow to an enemy, they are likely to defend it rather than take it head-on (provided they have shields). Couple this with the fact that some bosses retreat at certain Hit Point thresholds, plus the ridiculously annoying Ruina, it's almost as if the Destiny AI is savvy enough to know about the Game-Breaking Bug. Luckily, this only applies to the initial attack: enemies won't block if a Support Attack is what destroys them.
That One Level: Zigzagged with Scenario 23 where players must fight several Adrasteas charging a city area, but ensure they are not destroyed as per the Mobile Suit Victory Gundam plot. What makes the scenario bad is the "Mercy" Spirit Command note If the pilot's next attack would normally destroy the enemy it hits, so long as the user's skill stat (in Destiny, it's pilot level) is higher than the enemy's, that enemy's HP is reduced to 10 does not appear in Destiny AND unit weapon upgrades are linked (they cannot be upgraded individually in this game), thus players are forced to carefully calculate the amount of damage dealt towards the Adreasteas without triggering a game over. On the other hand, the Adrasteas will automatically defend any attack that would normally kill them, making it much easier to cripple them without destroying them. At the same time, players need to bring three enemy units with named pilots down to 20% of their Hit Points. As soon as it happens, the entire group retreats regardless of any other factors to take into consideration. Depending on the line-up of units players are using, this scenario is either this or a Breather Level.
The Woobie: Not only does Cliana lose her parents in her back-story, her adoptive father proceeds to experiment the hell outta her, until she ended up with a Split Personality. She gets better, though.
The Second Original Generation removes the experimentations: instead, Liana must watch as her sweet personality, Chris, that she accepted as an extended family member, vanish forever. Not only that, she also loses Ventus in front of her. Also, the one that stays is the crafted personality, and Chris was gone because of trying to save Glacies and Ventus in the first place, an act that was fully endorsed by Liana, so Liana has to live with the fact that she killed Chris, the original personality.
