I get those errors quite often while playing. Not sure what triggers them.
Here’s the logs:

I’ve had the same errors;
Screenshot of the first page of errors (Looks to be the same text as in the logs above)
and another one when loading a saved game.
I’d issued a massive loot command a while before saving then re-loaded and I get the error.
The save is here: http://1drv.ms/1KSqP2l
(I also have the earlier saves (before I issued the command) if you think it will help??)
