When Molten Iron exists in the Basin, placing the Casting Basin or Casting Table will cause the texture of Molten Iron to disappear, but the use is normal.

Hello again @Qi-Month!

I can't be able to reproduce the bug, I'm not sure I understand your explanation.
However, visuals bugs can be occured from others mods you are using maybe. It look like you are using a modpack. Especially Rubidium or Embbedium ?

Thank you for being very active in the bug report, it helps me improve Create Metallurgy.

If i don't have any news of this issues within few days, I will close it because no one else has reported this problem and I am not able to fix it.
