the Dwemer platform T_Dwe_DngRuin_X_Platform_02 (file path: tr/x/tr_ex_dwrv_Plat_02.nif) is lacking a proper collision mesh: the NPCs fall through the platform.
In the Daravel Ancestral Tomb, there is a skeleton that casts spells which damage skills. The only way to fix this is to leave the dungeon and visit a shrine which can restore attributes. This is a terrible thing because it means you will no longer be able to hit the enemy with weapons or cast spells which can damage the enemy after several seconds of fighting it. This is bad enough, but there is another, tanky skeleton who will get between you and the mage skeleton, and a greater bonewalker which willsap your strength and keep you from being able to dodge the spells.
At the end of the Rift questline, you meet a khajiit wizard who transforms into a tiger. The journal entry explicitly says that he has shapeshifted. But when you give the coded package to a prince, you have an option to say that he was eaten by a tiger who choked in the process. This player's reply should reflect PC's ignorance of the khajiit lore. But in this case, the journal entry should not have information that the wizard has shapeshifted. Sorry if my explanation is a mess >.<
