Title: Fix NPE when updating a coarser slot's state

It is not quite clear what causes a coarser slot's state to be missing but it is okay to set the state to 'Active' here if the stamp is missing.

While I was on this, I also simplified the math to compute slotFromFinerSlot. Also, fixed some typos.
