The first is being accused by NPC characters, of casting magic that I didn't cast. Like, you're standing perfectly still in Druid's Grove or Myconid Circle and suddenly a guard runs up to you with the narrator saying something like "casting unfriendly spells is a sure way to upset the guards" or something like that. It's happened a few times this playthrough. Once, it happened mid-way through a conversation with an NPC.
The second is in the Arcane Tower owned by Lenore the cleric of Mystra in the Underdark. I let a character get close to the Timmask spores and they started laughing. Then, when we walked away the laughter was still playing on a loop. Even as we walked out of the tower, the laughter still played on a loop. It was disassociated with the characters, as if it'd become an ambient soundtrack pegged to the spot where the Timmask spores were located in the tower, but I could hear it even from outside the tower.
