I don't know what exactly happened because I was away from my computer. I configured your tool to upgrade two of my LF-4 lasers (first from lvl 13 to lvl 16 and second from lvl 8 to lvl 16, both at 100%). I had enough uridium for upgrading and in the begining everything worked like a charm, so I went away from my computer. When I came back and checked the log in your tool then i saw something about an unknown error and one of my LF-4 lasers didn't want to finish upgrading at the state of 100% of time. I closed the tool and checked the logbook in the game and there was a lot of errors saying that upgrading to lvl 17 wasn't successfull. It's everything what I can say about that situation. I love that tool, you've done a very good job Bonge. Maybe in the future there will be a chance to get this bug fixed, however I don't know how to help you identifying it.
