Modding SW3?

As far as the Charon bit goes, I noticed that if you exit the Charon system, save, than load that save and enter back into Charon, the Templar ship list will be randomized again.

Edit: Forgot to post what I wanted to reply originally, have you tried jumping to a new system you've never been in before in that savegame, and seeing if your new items are being sold there?

Standard operating procedure for me to change systems when testing scripts.
