Wheatthin ran your mod list through Mlox. Thanks Wheatthin, BTW.
It appears you have two plugins that need to be cleaned of GMSTs and you are running too many of the Elders of Vvardenfell plugins.
There are other possible errors that Mlox could detect by running it on your machine (Mlox can't do some things from an external list, like update your load order).
Mlox is pretty simple to install and run. I really recommend you get it. It could possibly fix all your problems (no guarantees) and it will tell you about updates and patches you may not come across normally.
The GMST issue could be causing erratic behavior which is showing up as the error you're having.
I'm sorry, but I have to log out for the night (very early day tomorrow) but there are a lot of others around who can help.
HEY TETCHY! lol (it works at GHF, not sure about here)
Edit: Total ninja latendresse76
Got time to help out a little?
