OK. CarpetRegrid2::positions should be checkpointed and recovered; if this is working as it should (can you check your checkpoint files, just in case?), then something is changing these variables at recovery.

Is Whisky_MoveCarpetGrids perhaps reinitializing them? This will only matter if you're regridding at recovery (otherwise CarpetRegrid2 simply won't look at these values at that stage).
