Update: When the model is not simplified for symmetry (i.e the model shows the full region of examination) I am able to run to cycle 4 before getting the following error:

Problem terminated .... no cell controlling time step

Additionally, when I go to the View -> Plots tab and examine material location, my model does not show up on any cycle other than cycle 0.

 This is my error log:

Error! Problem terminated .... no cell controlling time step
