Not sure if this is related but I have now had these issues appear in Chrome, Edge (Chromium), and Opera as late as a few minutes ago:

1. Text that's been entered disappearing. (examples: a [ /p ] tag where the /p disappeared in the middle; text disappearing from articles, text in timeline events reverting to versions from two or three updates prior)
2. My timeline just vanished while I was working on it. I made edits. It said it saved. Then I checked, and it reverted, so I refreshed, then I just had the wallpaper, and I haven't been able to reopen it in Opera or Chrome.
3. I can view my timeline in my world but when I click the edit button, the edit options don't come back up.

I was able to make a new timeline this morning. But it wouldn't load after the fact. So, I'm going to swap over to the new ticket and move my notes there.
