Random pipe temp drop

Sorry, I'm not clear from that screenshot on what you mean by temp drop.

one segment of pipe had the fluid dropping in temp lower than all surrounding variables.  If you load the save but don't unpause you can see that from that corner of pipe works onward the fluid is colder in that area than it is both before and after that spot.  The "spot" is the top right corner of the right hand aquatuner

I am experiencing the same thing. One single pipe segment has entropy nullifier tendensies. It cools the liquid below ambient very quickly until the liquid freezes and breaks the pipe.

Load this save and watch for the broken pipe segments.
