Thank you.

After I added the call:

v_center->set_cell(bottom_12)

I now have a valid vertex. This answers my questions: my vertex didn’t have 
an incident cell. The next set of errors come from neighbor relations, which 
I will review, along with the flip_really() and set_adjacency() functions.

Inserted vertex -1.32816 5.74258 -1.06896 with timeslice 6
top31 has v_center
v_center->is_valid is true
Number of vertices after = 15012
Classifying simplices....
neighbor of c has not c as neighbor
