JS error on Topic page during timepoint generation

[ragesoss]

After the initiation of timepoint generation initiated by a topic owner, at some point the page threw a JS error:

I think we saw this same thing happen during a demo you were doing, @mattfordham.

Subsequently, refreshing the page worked and the timepoint data appears to have been generated properly, so I'm guessing this is just a UI error caused by an unexpected data environment.

@ragesoss I can sort this out when I do the step-wise UI workflow.
