I met the headless horseman for the first time. This is what I got: http://img13.imageshack.us/img13/8894/tesv2012021822331799.jpg

Im using ugrids=7 do i need to change the values on the the navmesh or something else in order for this stuff to stop. I have seen this happen before with other npc's on horses and random flying dead npc's.

So anyone got any navmesh values for me?...

I'm not sure what this has to do with the navmesh....do you have any active mods that alter horses in any way?

It always seems to happen when either loading in new npc's or in the case of the headless horseman he was running away from me at full speed a bunch of thalmor and legion guys spawned just in front of him and he tryed to avoid them and then spazzed out flew in the air for a while then stopped as shown in the screenshot.

Navmesh? just a guess as that can be raised to allow long range arrows to hit far npc's, at default it just goes through them.

No mod's for horses.
