Ok, hopefully this is a quick, easily, AI script-less fix...because I, as many other people I've noticed, can't touch scripts without the editor crashing. Yes I run it in administrator mode, yes I've tried it in compatability mode.

Here's my problem. I decided I wanted to "cheat" a little and fumbled my way through making a Khajiit merchant with a 10,000 gp limit and the lowest Mercantile score I could get. This has helped by making him a one-stop selling point for all my needs, at least armor and weapon-wise. Something about selling him potions and gems just seemed weird. Anyway, I've been using him for a bit and his inventory is getting rather...crowded I guess. He's got iron and leather armor from when I started playing all the way up to my most recent elven and orcish additions, and a whole slew of magic items I don't intend on using. Is there something I can do to get his inventory to "refresh" so that he only keeps a few items that I might stick in his container, and like with other cells resets himself every three days or something? As it stands the problem isn't too bad, but opening his buy/sell window does take longer than it used to now. Any help would be much appreciated guys!

Set his Merchant Container to respawn.

That sounds so simple. Thanks, I'll go and implement that right away
