First post here- my apologies for any incorrect formatting.

I have also had this exact same issue. Can be reproduced exactly as stated above. I have input energy through ender energy conduits, and the liquid inside is concentrated cloud seed. Hope to see a fix soon.

This was fixed in commit 9ba0554 (build 425), 3 months ago.

424 is 3 builds old. Could you try updating?
