Ship parts not counting as ship parts

[AHare]

I'm making some more ship pieces, but when I place them in-game they don't seem to count. If you have just the modded ones, they're not recognized as proper parts. I also made another ship beam, but it isn't can't be used for cryptosleep pods. I checked the C# source, and that I saw (I really know nothing about C# so I'm probably missing it), it just gets all the blocks adjacent to the core that count as ship parts, so I'm not sure why this isn't working. Anyone else got an idea? Are ships parts just not moddable or something yet?

Bump. Still can't figure this out.
