EDIT: Morrighan may cause disconnection issues. You'll have to wait until Exec is able to update it or try to hurry before getting disconnected.EDIT: Morrighan has been updated and should no longer cause any NGS issues.It turns out the server sends you a keyword that connects to the correct joe. Lucky for you, I have put together a list of corresponding joes.
Requirements
First off, make sure to download the npcinfo.english.txt and put it in your data folder. This will rename all the joes as No.1 and so on. There'll also be an id in parenthesis after the number, the keyword id, which you'll be obtaining from MabiPale.
Then download Morrighan and MabiPale. Follow the instructions in Morrighan's readme to get it loaded with mabi. Then start pale once you're ingame.
Once in game, click the connect button on MabiPale (do this before talking to Lorna. if you do a few things before this, a lot of other stuff will be logged, stuff you don't need). This will start logging packets. Make sure you start logging before entering the event mission. Once you load in, do a search (Ctrl + F) in MabiPale and type in "AddKeyword". Check the Ops and Recv check boxes and then hit Find Next.
Now you should see something like this on the right hand side
Op: 00005DC1, Id: 0010F00000044F3F
00001 [............2F3C] Short : 12092
Copy the Id after Short. In this case, it's 12092. Now go to the conversion list and search the id. The result should be found and next to it will say Number = 13. Then go back in game and find the NPC with the name "No.13 (12092)".
This isn't the most simple method, but it's currently the best method to quickly finding the correct joe. Make sure to hit Clear in MabiPale after each run so you're not searching for the previous keyword. And before anyone asks, you can ignore the Name in the conversion list. That was just a reference for me when creating the list.
Good luck yall
