Comment (by Samuel Cupp):

I’m not sure what your schedule.ccl currently looks like, but the master branch of `IllinoisGRMHD` only has those two functions (which I’ll refer to as con2prim) in AddToTmunu, not SetTmunu. Did you also add it to SetTmunu? All Leo did was change the scheduling from something that looks like

schedule con2prim in AddToTmunu

to

if(stress_energy_at_RHS)
{
  schedule con2prim in AddToTmunu
}
else
{
  schedule con2prim in HydroBase_Con2Prim
}
