Eh, something is still wrong. I think I know which one didn't load - which is odd since the included .lsx file was from a mod that required that mod first. But if I'm manually adding this in, I need to know what the point is of this line:
<attribute id="UUID" type="FixedString" value="6cdf7b52-6dd7-4d2f-88b6-745e7199ecef"/>
If I add in a mod manually, I'm going to need a similar value and I am clueless what this long hexadecimal string refers to or how I figure out what to put in its place.
