Any ideas on this steam fluid? I am just confused.

What is causing this? I updated thermal expansion to 3.0.0.2 and still nothing, Is it railcraft bug or thermal expansion bug? I cannot figure this out, the textures are fine in the corresponding folders aswell. Is it just a rendering bug? Can someone point me in the right direction on how I would go about fixing this, is there a new build of thermal expansion that fixes this?

Also if you can, could you link me to the new thermal expansion github or jenkins...
