reconstruct_Wv with cell centering violates angular momentum conservation

Roland Haas created an issue

we have a bug report that at least for cell centering the option reconstruct_Wv (off by default) does not conserve angular momentum. This system where this was observed was a torus around a BH.

    "We do have a bug report" isn't really so helpful. It would be interesting to have a parameter file that we could actually run and see the effect. Otherwise how should we go about even reproducing it?

    I suspect that one could use a rotating NS or so for testing. Let's wait if Vassilios has more details that he can provide. So far the ticket is mostly a reminder for Christian and I (who wrote the code) to look into this.

    CR: I don't know what reconstruction was used. We will have to ask.
