Thanks for the bug reports. If you have time, you should also report these to Larian's official bug report forum:
https://larian.com/support/baldur-s-gate-3#modal9. Dual wield does not add to AC during combat
I assume you've taken the Dual Wielder Feat - dual wielding doesn't add to AC unless you take that feat.
27. Also, if an enemy is pushed in an abyss and die, there is no way to talk to or loot his body. This is especially annoying if he holds some important story items.
28. In the scene when Neve and his grey dwarfs are defeated, if their bodies are in the lava, the bodies would disappear after a long rest.
These seem like features, not bugs. Push an enemy into lava/infinite pit for an easy insta-kill instead of fighting them normally? Okay, but you lose their loot.
35. The bonus action for great weapon master cannot be transferred to next round if not used in the current round.
...it shouldn't be transferable to the next round??? No actions are ever transferred to later rounds.
