Could you also send us the parameter file you used as well as the interface.ccl file declaring this variable? Maybe you want to attach this to a bug report in trac, so that all the information is in one place.

prolongation='none' is one of the possibilities; there are other prolongation types, e.g. sync, restrict, or copy.
To find out what is going on, we need to find out which thorn called on Carpet to interpolate in time for what reason. A stack backtrace or similar information would be useful.

Other causes for a timer interpolation may be a spatial interpolation at a time where the coarse grid does not exist, or a reduction operation at such a time (e.g. for scalar output).I haven't declared it with prolongation=none, but I never interpolate it, reduce it, or sync it.
How do you declare this variable? You may need to explicitly tell Carpet to leave this variable alone, or to report an error when such an operation is attempted.How do I do this?

Do you regrid at that time? It might happen that in order to regrid at that particular time Carpet would need to interpolate in time, and it didn't do before because levels might have been lined up at the time of regridding.
