We have identified and resolved the root cause, which was related to a schema change on a base table that wasn't reflected in a view against that table. 

Basically, a string column involving review task comments was made wider, but the view that feeds SEDE still thought it was shorter. A comment in the review queue for `Buddhism` (which exceeded the old length) was entered in the meantime, but this incompatibility wasn't spotted because the only views against it are the ones for SEDE.

- `Buddhism` has been corrected manually and is now complete.
- We are currently kicking off the remainder of the databases, which will take about 8 hours. Meaning the remainder will be completed by this evening.
- We have created a task internally to automatically refresh all SEDE-related views prior to the weekly refresh task.
