It was a problem with the Gibbs Reactor. Thank you for reporting. Fixed. Fix is available via CUP.

Thank you for reporting. There were actually two underlying issues, the big one being that information feed streams are eliminated from the problem as 'need not be solved' which caused the parametric input to go lost and the entire problem to be independent of anything. Fixed. CUP.
