Pretty simple reason. I deleted all of my original files a while ago because I wasn't satisfied with where I was getting and abandoned the project. Luckily I kept a copy of a more recent workprint than the one I had previously released and was able to make some final fixes and cleanup off of that. However, If I wanted to make more radical changes I'd probably need to recreate the project from scratch
I may consider a v2 with some simple changes if many people point something out that needs fixing or could be improved, but nothing radical at this point.
As as for tying Qui-Gon in at the end, I just couldn't do it in a way I was satisfied with. Adding the final scene on the Tantive IV just added too much to the running time (truly only a couple minutes but I was trying to get as close to normal Star Wars length as possible) while adding too little to the narrative.
I will consider it if I do ending up creating a v2
