No worries. Using the @ means we get a notification, one or two is fine, but it's become a habit and 15-20 notifications means the panels get overwhelmed. If one of us has missed a reply for a few days it's a different matter, except it's buried in the unnecessary notifications....

Back to the problem.
How are you dissolving the gas? Real gases aren't great around the phase change point. I tend to use ideal gas (if possible) and then set liquid species densities with temperature (liquids don't compress much), the phase density should follow with composition. If you monitor phase mass, species mass and mass transfer during the simulation is it a gradual loss or intermittent?
