Using a Tamriel_Data head on your player character and adding the "vampire sun damage" spell correctly replaces the head with the generic vampire head. Removing "vampire sun damage" then does not put the original head back, but removes the head body part entirely.
I've only tested this by consoling player->addspell "vampire sun damage" and player->removespell "vampire sun damage" but since the vampirism cure script does essentially that, it's fairly safe to assume using a T_D face, becoming a vampire and then curing yourself via the quest will take your face off.
On the top exterior floor of Dreynim spa (the one with the hot pool), there is a piece of Mournhold set railing that you can fall through if you jump on it. It's ID is t_de_setind_x_dwall_01. For some reason, only the eastern railing does that, even though the railings on the other two sides are exactly the same piece. See screenshot; the piece in question is under the crosshair. I am using OpenMW nightly 20200219, TR v. 19.12, and T_D v. 7.1 (low-res).
T_De_IndBonemold_Cuirass_01 has no skinning. Ingame it's obvious that it doesn't work but it's already used a lot (maybe there's a non bugged version in older data?) It's from the vanilla Gah-julan cuirass
This error concerns a missing mesh or texture in the stated file: T_Com_SetHarbor_Fishnet_01
Two of the four corner ropes on this net have the top part of the rope visable, but the underside is not present. I found this while building a claim, not while I was ingame.
So, I was hoping by now this would get fixed but it looks like it won't unless I report it. I figured it was an obvious issue. Anyway the weapon "Orcish Longsword" has a clipping problem when held. I've enclosed a screenshot of the issue below.
And before anyone asks, it affects vanilla hands too so it's not a Better bodies related bug.
the texture looks really bad both from first and third person stats are also quite weird for such a chep weapon: higher dps than a silver claymore, while also being one-handed https://imgur.com/a/kUAj7
