Unfortunatly, unless you dont have a AutoSave before the new command, you're out of luck

..
However, don't count a Porpoise out of the fight so soon, albeit it may have some disadvantages compared to the Gar, be patient and it's just as lethal..
So, in answer to your question, unless you don't purge your saves, your screwed (pardon the language).

Krauter
