Game Breaking Bug: Doing Raid the Grove on my evil character having already killed the druids and like half the Tieflings (hey it was a confusing battle okay lol) before ever even talking to Mithara, Mithara gets stuck (i.e. her AI breaks; not physically stuck) just standing in one area near the cliff with 4 goblins and just says there's more and to kill them or whatever. I've read she's supposed to go into the stone door down to the left and kill some cows and people but I already killed those people. All the druids and tieflings are dead, in fact. So if things are done out of the order it wants it seems it breaks the game. Some people talked about it here.

Glitch: If you pet the dog Scratch in camp it'll give Shadowheart, Gale, Wyll approval. Infinitely. You can just pet it over and over.

Glitch: Similar to the previous, this one's for Astarion and Lae'zel. Outside the hag's shack if you drink from the well it gives them approval. You can do it over and over.

Bug: The level 4 light cleric bug that was known to affect Zariel Tieflings preventing leveling up due to not enough cantrips also affects Asmodeus ones. Probably all of them tbh.

Missing content/bug?: When the Tiefling guy is supposed to show you the stars in camp, he doesn't. Similarly, when Shadowheart was supposed to be experiencing her new powers with some animation I didn't see any animation or vfx or anything. So I don't even know what it was supposed to look like.

Bug: The goblin guy outside the windmill if you knock him out so Wyll can talk to him, you can't actually talk to him once he's unconscious. The talk button drop down does nothing. In fact, after awhile the talk option disappears entirely and it's just like loot and attack and whatever.

Bad design: Charm Person doesn't actually make someone not able to attack you as it should in 5e. It's effectively just Friends that you can use in combat and wastes a spell slot (as that is a cantrip).

Bug?: During battles sometimes what should be allied forces have red icons (and they take god awfully forever for big battles to actually DO anything) and also attack you. Happened when attacking the druids for the Tieflings. The Tieflings also turned against me but after the druid leader was dead and the Tiefling leader died the fighting immediately ended and they acted like they didn't even know I killed like half of them in the process.

Bad design: Everything has hyper inflated HP and AC in some cases as well. There's also ground effects everywhere. Poison, fire, oil... it's total madness.

Oversights: There's a lot of instances of NPCs I've killed - literally with necrotic damage (you don't come back from that in D&D outside of something like Wish maybe), which are magically back to life. The Mindflayer on the ship for instance. Kill him and the demon dude, he's back alive as soon as I connect the tentacles as the ship is going down. Also alive once the ship finishes going down and is getting dug up. Had a similar thing happen with Rath. Killed him with necrotic (along with all the other druids). Once Raid the Grove started he was magically alive again and presumably filled the entire bottom area with poisonous clouds (which is absurd btw).

Bad design: Fire bolt should be 1d10. Not all cantrips are equal with 1d8, that's just not how 5e is designed. Heck poison spray should do 1d12. Also mage hand appears unable to actually float vertically, which makes it virtually useless. It should be able to float up to untie a rope for instance (which would be useful in at least 2 situations).
