Christian Ott found that right now the scheduling of EinsteinUtil/SetMask_SphericalSurface::SetMask_SphericalSurface and HydroBase::HydroBase_InitExcisionMask conflict in the Post_Recover_Variables and INITIAL since SetMask_SphericalSurface which needs to run after HydroBase_InitExcisionMask is scheduled GLOBAL which happens to be global-late in these bins. SetMask_SphericalSurface must be local since it must run after SphericalSurfaceHasBeenSet which is after SphericalSurface_Set which is GLOBAL.
The attached patch runs HydroBase_InitExcisionMask global-early loop-local instead. Pleas note that the patch will change the behaviour in PostRegrid slightly since HydroBase_InitExcisionMask (and not just SetMask_SphericalSurface which already does so) will run on all refinement levels, always, independent of the iteration counter and Carpet's do_every logic.
The current code prevents properly recovering from checkpoints.
