Ah, that's been a long time. I am investigating that now, though I am
not aware of any change that could have introduced that.

The point was that if you save the simulation to XML, you should get the
exact same state when you reload and run, including timestepper
settings. If you activate timestepper in the preprocessor, it will be
turned on when you load the xml.
