With every big patch comes lots of bugs and glitches. Plus, I think we're overdue for one of these, so why not?
1. Nightpriest Assassins summon the little purple spiders from the Seed.
2. Transforming Dark Jr. Yeti transforms into a regular Dark Yeti instead of a Transformed Dark Yeti. (and yes, this does matter, since the transformed version gives double the experience.)
3. Lakelis, Tory, Ellin, and Wonny are not available for regular PQs, and thus, the regular PQs cannot be completed (on top of that, a certain quest in Kerning City cannot be completed because it requires you talking to Lakelis).
4. Non-KMS mobs were unchanged (though this could just be due to not caring).
5. Magnus's sword charge attack now hits you twice, once more after the animation ends.
6. Morning Star/Frozen Orb/Bat Swarm/Wingbeat/other skills of this sort attack a lot faster than previously.
7. During the One Card mini game you can lock down a game by not choosing a card (when you use the colour changing card) within the given time limit. After the intended game time finishes, the player with the least card wins(you can intentionally abuse this to secure a win).
The Battle Mage Aura glitch Green4Ever mentioned.
9. Arrow Blaster doesn't hit mobs.
10. Account buddy is glitchy in showing people who are actually online.
11. Monsteropoly can disconnect people at random.
12. Monsters that were changed did not have their drop tables updated.
13. The map crash involving Zero and transformation potions.
14. Some people don't always get Bingo invitations (could not be a glitch, but idk)
15. Monster Park levels are messed up.
16. A lot of people are unable to use the new Inner Ability UI, crashing or glitching.
17. Pierre and Crimson Queen don't always give a box when killed.
18. Some people cannot type in all-chat properly.
19. Zakum's 1/1 damage doesn't apply to mechanics in hovering mode (a good thing, but still a glitch)
20. 8 slot coupons do not work if you have more than 88 slots.
21. The Contract of Darkness for the quest "Preparing for the Revival" doesn't drop from Coolie Zombies.
22. Sap of Nependeath for the quest "Elma's Nependeath Juice" doesn't drop from Nependeaths.
23. "Life Alchemy, and the Missing Alchemist" is broken in that Russellon doesn't acknowledge that you used the pill.
24. The Fairy's Tea Leaf for the quest "Queen's Tea" doesn't drop from Desert Rabbits.
25. Old Pieces of Map for the quest "The Scattered Map" don't drop from Hectors, though they should.
26. Luminous cannot finish the quest "Finding the Final Augury".
27. Zero does not receive the quest "Excessively Charming" when reaching level 30 charm.
28. Smithing cubes cannot be used on Jett's Core.
29. Jett cannot open the Core Aura UI.
30. Jett cannot add points into Hero's Will.
31. Floor 24 of Tower of Oz does not accept "Heliseum" as an answer for the Retake BGM.
