Dunno if it's possible to do. I would my merchants to not save at all with their equip, etc. So we can easily manage the creation of them at each startup with the newest system added in distro097.

It's already in 098. Reach the Changelog for 098 Beta.

All items within their wornitems is not saved also (so means all equipped items). If you use additional storage (not handled within worn items container), then you must clean that up on your own.

Oh MY! NEGATIVE time for implementing a feature! This one is a winner!

Damn I didn't remember it was in the changelog... SWEET!
