I built a DEUT reactor, and the water slowly disappears from the cooling loop.
Steps to reproduce:
1. Open save (https://powdertoy.co.uk/Browse/View.html?ID=2969823).
2. Press the "F" button and wait for DEUT to fill the reactor.
3. Press the "N" button and wait for around 3 minutes.
4. BOOM! 90% of water magically disappeared.
The water is not escaping from the loop.
Is it a bug?
Thanks, it solved the problem :)
Didn't know that wall can destroy particles, I thought it just pushes it out.
Solved.
