This is probably a different scheduling problem.  Boundary conditions  
need to be applied after regridding and after restricting; maybe this  
is missing?

Exact should probably be scheduled at
	postinitial (or some other initial bin)
	postregridinitial
	postrestrict
	postrestrictinitial
	post_recover_variables

... essentially in all the places where MoL_PseudoEvolution is also  
scheduled.

Prestep and evol are scheduled right one after the other; scheduling  
in these bins makes no difference, except that everything in evol is  
scheduled after everything in prestep, which may help certain  
evolution thorns.  I think prestep may be better for Exact, since some  
thorns schedule "in evol after MoL_Evolution", and this would then not  
necessarily be scheduled after Exact.
