Sanae	Last Wish	Also has the effect of Divine Protection of Moriya. Buffs are a static 33% and don't scale with level.
Satori	Spellcard Recollection	In the spellcard menu it only considers the base cost of the spell, only adding the extra MP cost afterwards, this makes it possible to ignore the extra MP cost.

Rin	Blazing Wheel	Has +3800 ACC.
Parsee	Jealousy of the Kind and Lovely	Doesn't actually deal increased damage based on TRR duration.
Yuyuko	Ghastly Dream	Instead of reducing the ATB of all enemies, it reduces the ATB of the selected target multiple times (equal to how many enemies there are).

Byakuren	Skanda's Legs	The SPD buff isn't increased when she kills an enemy with this spell.
	Magic Milky Way	The debuffs get weaker as the spell levels up.
Nitori, Eirin, Ran	Cooling Down	The skill activates even when HP is not full. However, it does not work if the character has their current HP over max HP (by the effect of Eirin's Healing Limit Break.)
Nitori, Utsuho	Overheating	The counter is removed even if you switch them for another frontliner.
Renko	Ability to Read the Moon	Learning this skill instead gives you the effect of Ability to Read the Stars (this means that there's no difference between learning either skill, and learning the other one afterwards has no further effect)
Strategist	Inspirational Plan	The skill's effect also is applied to enemies.
Healer	High-Level Treatment	The skill's trigger rate was much lower than the stated %.

Miscellaneous Bugs
When using options -> return to title screen from within the dungeon, the "consecutive battle bonus" is not correctly reset.
1F Forest Fairy's attacks do not have sound effects.
Due to how the game handles ACC and EVA, Patchouli's 0 base EVA rounds up to 1 when she doesn't have any other sources of EVA increase.
Debuff resistance increases the strength of received debuffs instead of decreasing them.
If you begin a New Game + with Renko and Maribel, the achievements 97 and 98 will be instantly completed and make the 3 Deformed Bosses disappear from that playthrough.

Plus Disk 1.107

Plus Disk fixed many of the bugs present in the main game, but there are still some that remain (luckily most of them are fairly minor).

Skills and spells that function differently from intended
Character/Subclass	Skill/Spell	Actual Effect
Elementalist	Element Memory Defense	Damage reduction also reduces healing received.
Appraiser	Kill Bonus- Drops	Actually increases item drop rates by 40% instead of 16%
	Daily Toils, Basics of Business, Aesthetic Sense	When Appraiser is in the back, gives flat bonuses independent of SLv, instead of 2/3rds of the bonus when in front
Reimu	Barrier Expert	Paralysis effect also applies to Auxiliary spells, meaning she can inflict herself or her own allies with the ailment.
Rumia, Cirno, Wriggle, Mystia	Going it Alone	Despite the description saying it checks the entire party of 12, it actually only checks the front line. So you can potentially stack it with the Team ⑨ boost through Proof of Kinship. Also, because it specifically checks if there's "only 1 frontliner that can learn Team ⑨", you actually lose the stat boost when no Team ⑨ members are in front (because 0 is different from 1).
Rin	Hell's Necromancer	Doesn't actually nullify the all stat reduction.
Rin, Sakuya, Yuuka, Nazrin	Extra Attack	Spells which cost 1 MP can be repeated even when the user has 0 MP.
Suika, Yuuka, Momiji	Encounter with a Strong Foe	Works even if the user doesn't attack, such as when using Auxiliary spells or Concentrating (except for Form Change).
Mokou, Kasen, Utsuho, Kokoro	Fighting Spirit	Damage reduction also reduces healing received.
Parsee, Hina, Rin	Two-Way Curse	Damage reduction also reduces healing received.
Satori	Spellcard Recollection	In the spellcard menu it only considers the base cost of the spell, only adding the extra MP cost afterwards, this makes it possible to ignore the extra MP cost.
Mamizou	Monster Tanuki Prankster	Occasionally, if an attack that inflicted SHK also deals enough damage to kill the enemy, the SHK status tooltip won't be displayed.
	Slippery Tanuki Disguiser	With multi-target attacks, the DTH chance is added again every time an enemy is SHKed, calculated individually per enemy in order of left to right, front to back; which means different DTH chances per enemy depending on their relative position. This can cause DTH to be inflicted on targets that weren't actually inflicted by SHK themselves, and means that when SHKing multiple targets at once, the enemies later in the order will get higher DTH chances.
Eiki	Rod of Remorse	The MP recovery effect works even if the user doesn't attack, such as when using Auxiliary spells or Concentrating (except for Form Change).
Eiki	Ability to Judge Morality	The effect where Cleansed Crystal Mirror's damage reduction activates from the back doesn't actually work.
Utsuho	Self-Tokamak	The effect where Overheat no longer increases MP costs of attacks causes Normal Attacks to restore MP based on Overheat level.

Miscellaneous Bugs
Due to how the game handles ACC and EVA, Patchouli's 0 base EVA rounds up to 1 when she doesn't have any other sources of EVA increase.
While the deformed bosses still disappear when you start a NG+ with all characters, now their bestiary entries are at least automatically filled.
Achievement 30 (which gives you your first Jewel of Greater Awakening) checks whether you have 12 Stones of Awakening by adding up the number of Stones you have in your inventory and the number of characters that currently have a subclass. Due to an oversight however, it does not check for subclasses on any Plus Disk characters, which can cause you to not get the achievement even if you have already found all 12 Stones.
You can bypass the Hard Mode Library Level cap by using the A button to increase 10 levels at a time.
If you lose in any of the boss fights where your team members have Elemental Blessings, those Blessings will be kept once you go into the Tree or Infinity Corridor (they'll however disappear once any event is triggered or relay point stepped on, which means the Blessings can only be kept on 1F or the Infinity Corridor).
Bloodsoaked Sword Skeleton can cause the game to crash due to how it uses 2 attacks in a single turn: this happens when the first attack triggers someone's Counter but the second attack kills them before said Counter can be executed. This doesn't happen with other enemies that use multiple attacks in a turn because in their cases, Counters are executed between each attack, instead of at the end of all attacks like with the Bloodsoaked Sword Skeleton.
If a character that was going to trigger an extra action due to Extra Attack gets killed by a counterattack, the game crashes.
