I initially came to report what I thought to be a card disappearing from under my cursor. What I observed was, I put my cursor near a card I recently created, and I think I was trying to click on it, or click near it. As soon as I did that, it disappeared. After investigating the logs, I observed that somehow its position was changed—the y value went to 0, so sure enough, when I scrolled up in the space it was there. Here is a screenshot of the logs:
The card id is D4UoKhy3fq7TgcAdRHJZN, the text is “On and On”. No console errors, no collaborators, no other clients. Just a weird occurrence…
