Water generating while using infinite storage

When I used debug's Ctrl+F4 mop command, I found that the liquid in your infinite liquid chamber had 2 tiles of liquid in it.  I had to mop it twice.  I've never seen that before. I wonder if you passed some "maximum" storage amount, and then the game made another tile, and then things started going wonky. 

I did not see infinite growth of the liquid when I opened the game.  I noticed you have several mods install. First thing I would do is uninstall all mods, try to replicate the bug when no mods are installed, and then add a new upload.  Right now, this could be a mod issue (might not be).
