Comment entries left on events are disappearing

A few hours ago, I left some notes in the “comment” field on a timeline event for an individual in my tree. Just now I returned to add more to that comment, and the text I’d put in earlier is gone.

I’d left a suggestion a few months ago regarding these comment fields, which I just looked at again to remember which other ancestor it was I’d used the comment feature on. Here’s the screenshot from that old comment. I went back to this event in my tree, and sure enough, this little comment is gone, too.

This is very odd. I’m sorry about this. I have a record of a comment being added on that tree on March 31st, and then deleted 44 seconds later. Those are the only records I have for comments on that tree. I will do some testing on comments to see if I can learn more.
