The GRMHD, SRMHD, and EulerFlow error plotters seem to not work correctly (The ADERDG correctness is broken (GRMHD AccretionDisk 2D/3D) )
The errors in the AccretionDisk3D, GRMHD application, looked very good (max mesh ref = 0.5
on a domain 0.0 .. 2.0
in x,y,z) one week ago:

The solution was stationary and the errors should always stay in the same order of magnitude. They did.
Now, we experience something different both in 2D and 3D ADERDG and probably also in the FV scheme (but this could have another source).
This ticket shall track these problems.
