Here are a few more bugs that I've encountered as I've played. I'm sure some have already been reported, so I'm sorry for any unintentional repostings.
-Looting containers or corpses in the Burial Isle section of Twin Elms stopped being possible, although gathering plants was still possible. Restarting the game fixed the bug.
-A barbarian using jolting touch procs carnage attacks that do jolting touch's damage, making it brokenly OP.
-The Adragans and Xaurips surrounding the Adra Dragon can be killed without pulling the Adra Dragon. This is on PotD and after alerting the dragon hunter to the Adra Dragon's ploy to take over her body... if that's the result of its soul not being in its body it makes the fight way too easy.
-If a Shadow Drake is killed with one hit its death doesn't update the bestiary.
-During a conversation with Aloth in Breith Eaman, before heading down to Sun in Shadow, Durance interjects but it doesn't show his portrait or even his name in the dialogue box.
-During the battle with Thaos, combat doesn't pause once the dialogue is over. In addition, tab doesn't show any information. It's also weirdly laggy in that scene in general.
-During the conversation with Hiravias after defeating Thaos, the bottom half of the text in the second section of his speech is grey instead of white.
-After slaying Thaos and reloading a save with him slain, his body is gone but his name tag still persists when the tab key is pressed.
