Patch

While this might fix the crash, I think it's the wrong fix.

A cell with a null structureID has been garbage collected. You're lucky if you find the null structureID -- that happens soon after sweeping. If you're unlucky, you'll just get garbage memory, or a crash.

We need to investigate how cell got garbage collected in the first place.
