EmptySet response when using Distillation Towers with multiple outputs

[clzola]

I am trying to generate a graph for cetane-boosted diesel from oil and fermented biomass, and I am getting following error message;

/src/graph/_solver.py:319 WARNING EmptySet response - likely overdetermined
/src/graph/_solver.py:355 INFO Searching for inconsistency in system of equations...
/src/graph/_solver.py:411 WARNING Refer to graph for more information.

If I make my DTs to have only one output everything works, but having multiple outputs seems to make a problem...

Here is the yaml file:
