After regularly having problems with Dragonborn, I tried the Miraak quest in Apocrypha again yesterday. Usually I got the bug when he becomes unkillable in the middle pool when supposedly killing one of the dragons and stealing his soul. Funnily this time it worked, though with another quirk. He only killed Salonikhir (is that correct?) and died/was killed by H.M. before he killed the other two. Which lead to a new bug that I couldn't use the book because the other two dragons were still circling as enemies above. (after using bend will shout on them and then killing them myself, the book worked as advertised). Unfortunately though, Miraak had virtually no "Miraak loot" on him. I noticed similar missing loot with the mask missing on one of th dragon priests in the Skall village quest with the researcher and a few other times. Is that a LotD problem? As I mentioned before, I have also repeatable problems with the sorting function, that certain fossils or weapons are not put on the shelves in the museum automatically.
