OK, I've continued to run into problems trying to port mods with the TTW conversion script. Things aren't showing up. For this one I followed the porting instructions verbatim that are found here:

Target was this addon for Orion's Gate, which has been imported to TTW by others and I downloaded without problems:

Nothing seems to have happened, so I ran FNVEdit on the file and this was came out:
[01:44] Background Loader: [The Librarian - Market Comes Alive.esp] Building reference info.
[01:44] Background Loader: <Warning: Unused data in: \ [0E] The Librarian - Market Comes Alive.esp \ [23] GRUP Top "NAVI" \ [0] [NAVI:00014B92] \ [3] Unknown \ [1] NVCI - Unknown>
[01:44] Background Loader: <Warning: Unused data in: \ [0E] The Librarian - Market Comes Alive.esp \ [23] GRUP Top "NAVI" \ [0] [NAVI:00014B92] \ [3] Unknown \ [3] NVCI - Unknown>
[01:44] Background Loader: finished
Any idea what this means? Nearly every mod I've attempted to port has loaded properly in the sense that there's been no slowing or crashes, but nothing shows up on the map. Method has always been porting it to the letter, as per Chucksteel's instructions.
