The current version of the flux limiter leads to a loss of energy at the end of the Evrard test, so that the total energy conservation becomes worse than for the version published in the code paper.
However, the old version of the flux limiter leads to problems with the vacuum test.
It is not clear if there is a way to make both tests work with the same flux limiter. It is pretty clear that vacuum cells will always cause trouble and we should try to avoid using them as much as possible.
That said, it might still be useful to have a look at this.
