Urgent, missing all comments in trello board, did they get deleted?

Question

I opened some cards on my board and they say they have comments, and I know they exist, but now when I open the card they are missing.

UPDATE: This is really severe since ALL comments from the board seem to be gone!

UPDATE: For this board, all the comments are even missing from the JSON export!

Under activity there is nothing as well

Thank you for testing @Kaylani Lau! We'll need some additional details that you couldn't share publicly, so I've created a ticket on your behalf to keep troubleshooting. Please let me know if you received an email notification for this.

* No the comments were not added that day, they were added throughout the whole week. 
* If I add a new comment, I do see the number of comments increasing and that new comment shows.
* I used Chrome initially and now after trying Firefox, the issue persists

Hi @Kaylani Lau!

I'd be glad to troubleshoot this issue with you. Were the comments added to the cards today? If you add a new comment, do you see the number of comments increasing?

Also, could you please access the board using a different browser and let us know if you experience the same behavior?
