201 courses are impacted for this.
Salesforce bulk_load does not preserve order, meaning that our comments that our users read are out of date.
We'll need to rectify this, and our plan going forward is as follows.
Warning: DO NOT DELETE ANY PUB ORGS, COURSES, COURSE RUNS, OR CASES
Verify that there have been no new FeedItem comments added to Salesforce. If there are, manually drop the historical FeedItems for that Case. OTHERWISE, bulk drop them for that salesforce_case_id. Verified!
Modify the bulk load script when creating comments to pass in a flag that will overwrite the CreatedAt stamp, but ONLY from the bulk load script, not on new comments
Enable the Create Audit Fields flag in Salesforce to allow us to overwrite the CreatedAt timestamps Done for sandbox + prod
Re-run the bulk load commands for all partners
