Could just be me but when I put the infinite heavy water tank into a fluid container (such as a tank), it won't fill up. I have double checked the fluid identifier and all.

I forgot to say, I'm using the latest version of NTM

Works with regular water fluid identifier, I'll reopen if the problem persists.

the infinite water tank items are specifically for water, nothing else. not even heavy water

Sorry to waste your time. Keep up the good work!
