・Aela
Aela becomes invisible during the quest of Silver Hand's one scene when she turns into a werewolf. She is still there though and goes back to normal after that quest. Please disable Bijin warmaidens.esp on your mod manager or skyrim start menu during only that quest if you worry that bug.
・Delphine
Her hair will clip her hood when she is talking with Farengar on the quest of Bleak Falls Barrow.
