Yep just what Svosh up there said.
There are other kewl things along this line as well. Some scripts won't fire on the Hawk while others will. If you run into another try talking on the hawke and then off and see if it helps.
Also if it's your first run through with USM installed I'd highly recommend scrolling up to Big T's starter post for the thread and downloading the fixes some are need to download some are elective depending on what other mods you have installed. All explained in detail in T7's post.
Now that we have all these new "improved" sabers no one will ever use the standard...lol
