Comment (by eschnett):

 There are two different groups, MoL_PostStep and MoL_PostStepModify.
 PostStep is supposed to be a pure projection operation that can run at
 many times, while PostStepModify is supposed to run only during evolution,
 e.g. to enforce constraints, at well-defined times and as part of the
 evolution scheme.

 Could it be that Con2Prim should be run in PostStepModify instead?

 While PostStep may not be required for ADMBase, there are other cases
 where it is required, e.g. in unigrid simulations where ADMBase is not
 evolved, or in other cases where some variables depend on others.
