But what could that be? This is with five or six different mod set ups over several years - and I'm seldom using Realistic Force, for example, and not now. What can affect it?

Do you have something that might alter the horse skeleton? I don't have any problems with that horse either... I've actually tried to loot it a couple of times, so I'm there long enough to notice.

Now I am usually running Slof's horses and Ulrim's, so I don't know if that's part of it or not...

Not sure - have to check that. Using MMM which has Slof's horses but it's a rather new addition so couldn't be it on earlier occasions.

I happen to have a save just there and loading it several times I notice that it's random, so it happens perhaps 50/50. I also think it's because it's a bit dislodged from elemental spell casting, as it's right by a spawn point. Anyway, a small annoyance - just wondered what it is that causes corpses to move freakishly at times.

The Havok implementation in this game was never very good. Things flop around all the time (or in some cases, fall right through the surface they were resting on). Just one of the many annoyances we must deal with in this game.

Yes, I was wondering about that too. I had this NPC, I think a trader in the Kvatch camp called Sigrid. She was stuck in a tent and twisted around horribly. Then she screamed
two times and she was dead! Guess I have to resurrect her at some point... These twisting corpses, I observe them now and then. It has been years since I played vanilla Oblivion, but I think I remember this to occur in vanilla as well.

Also, I guess it is quite normal that if you enter a guild or a shop you hear this noise and all items in the area (weapons, things on the tables etc.) move/jump around a little bit. These glass showcases very often contain "vibrating" items... ??

Stretched and horribly twisted corpses are almost always from a bad setting in oblivion.ini. Look in the [HAVOK] section for bAddBipedWhenKeyframed=1 and change it to 0. Oblivion needs it to be 0. FO3 and later need it to be 1.

If corpses are shaped okay but just moving a bit, I just think of them as not quite dead yet.

The items bouncing around in stores might be from the "Max Picks" line in that same ini section. I've seen people reduce it from 40 to some lower number to improve performance, but then Havok can't manage all those items. Changing it back to 40 might fix it.

Hm, thanks Supierce. The settings are at 0 and 40, respectively. So, these thing occur also with the standard settings. I am curious if somebody knows a cure...

Im having issues installing the supplementals patch via OBMM. when i try to add the archive or as a folder i get a warning message about multiple esp's. I went ahead and no esp's were on the list so i must of done it wrong. Can anybody give some advice on how to install this through OBMM.
