@AayushSabharwal did some of the cases of initialization with array variables simply require it wasn't using the initialization? |

I don't think so, they should just work |

InitializationProblem is not always built, however it missed a case. If you have an ODE and you define all of the initial conditions, then it does not need an initialization problem. But, if you simplify down to an ODE and give initial conditions for all of the original variables, including some simplified out, then you have defined initial conditions on some observed quantities and that needs to be accounted for by an initialization process. This fixes #2619
