Hi Jonah, I guess you might want to try turning "Weld vertices along edges" on or off - there is a slightly different mechanism used for both texture and normal maps in the LWO file depending on whether welding is enabled or not.

One for a style where there is one UV or normal stored for each vertex - this is used if welding is turned off. But if welding is turned on then it uses a different way to specify them that lets you specify different information for each face instead of only per vertex - this is for the spots where you have one 3D vertex in common but different normals and UV coordinates on different faces that hook into that vertex.

Maybe that has something to do with it...
