Can someone please give me a firm answer on whether or not Thermal Expansion Fluid Transposers do or do not have ModTweaker support as of 08/13/2019... there is an infuriating amount of incorrect information, old and incorrect script syntax examples... and just plain outdated information all over google when I try to find out why my scripts don't work. I have been through numerous forums, sites, wikis, Craftweaker, Modtweaker, and Gits for everyone involved, and I can not get results... even simply copy and pasting the example scripts.

As said on the official wiki. Yes.
