First off, I'd just like to thank KFC for NPCSpawner+. Without it, I never would have even considered working on DateBound!

So after you have the NPC Maker 3000 (Floor or wall version, it doesn't matter), the very first thing you'll want to do is click the "input override" text box. You need to type this exact line:

insert additionalnpctypes crewmembersobff

After that, it should say "Added crewmembersobff", and then warn you about 1.3 changes. This is good; we're ready to go on to the next step.

Now you need to click on the big "GENERATE" button if you're not already there, then click on the NpcType tab. In the search bar (where the input override bar was just a moment ago), type in sobff to find the DateBound NPC type. Give it a click and then click "Activate" to confirm your changes so far! This will prevent the 1.3 changes from forcing us to input the override for that same NPC every time we open the interface.

Understandably, you probably want to do more customization than that. Now would be a good time to gather any clothes and weapons you want your NPC to use. Once you have all that prepared, you can open up the NPC Maker 3000 again and follow the instructions that KFC has laid out for you in the interface to fine-tune your NPC to your heart's content!

If you're still having any issues getting this to work with NPCSpawner+, post down below with a link to your starbound.log and I'll see if I can help!
