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).
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.

I am unsure how the times could have gotten out of sync at such a late time in the simulation without getting out of sync earlier. I also do not understand why a time interpolation should have been attempted in the first place. I don't sync or attempt to interpolate this GF.
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.
