Old description:
Trying to run the par/qc0-mclachlan.par in the ET trunk gives the following error:
INFO (AHFinderDirect): proc 0: searching for horizons 1,5/6 WARNING level 0 in thorn CarpetInterp processor 0 host kop193.datura.admin (line 1683 of /home/ianhin/Cactus/etrelease/arrangements/Carpet/CarpetInterp/src/interp.cc): -> Grid function "AHFINDERDIRECT::ahmask" has only 1 active time levels on refinement level 1; this is not en ough for time interpolation
See also #373, which might be related.
New description:
The number of timelevels for AHFinderdirect::ahmask has to be set to something intelligent. Setting it to some fixed number doesn't work, because the number of timelevels for a given time-integrator might be different and Carpet chokes in that situation. At the moment it's set to how-many timelevels ADMBase::metric has, but that's also not good because that might be 1, while ahmask should have more. We cannot couple AHFinderDirect to any evolution thorn or Carpet as well. We might have to introduce a new parameter, but I would like to avoid this if somehow possible (which is why I coupled it to the metric in the first place, hoping this would be ok, which is apparently not really the case).

Comment:
We now set the number of timelevels for the metric to three, which solves the problem for now. I change the description to match the problem which is not really solved.
