In my never ending pursuit of escort ship perfection, I came upon the idea of creating a "clone" of the ships I use as escorts, so I can tailor their settings to my liking without screwing up that ship for everywhere in the game; ie: Instead of editing the Zidara ship resc, thus changing ALL Zidaras, instead making a copy of the resc and assign a unique ID and name (THE Zidara, for example).

Unfortunately, it seems that the game doesn't like this, as it crashes upon pressing the "Enter Ship" button. Any ideas?

Did you duplicate the ship's spďn resource as well?

Since the topic title has "EVN" in it, I'm going to echo David's question, except in reference to shän resources.

Check out the link in my sig for a package called EVO Extras. It includes a plug which creates clones of a number of the more powerful perses found in the game, allowing you to capture them (either for yourself or as an escort) and still keep all their weapons and shields.
