Comment (by Roland Haas):
Writing my own parfile:
``` ActiveThorns = "Time MoL" ActiveThorns = "Coordbase CartGrid3d Boundary StaticConformal" ActiveThorns = "SymBase InitBase" ActiveThorns = "IOUtil" ActiveThorns = "Carpet CarpetLib CarpetRegrid2"

I can get a error similar to what is being described in the ticket. My guess is that this branch rhaas/poisonarray ([https://bitbucket.org/eschnett/carpet/branch/rhaas/poisonarray%5D(https://bi...) will fix things since it applies the same logic as is used otherwhere in PreSync.cc to [Poison.cc](http://Poison.cc) when it come to handling non-grid functions.
