@johncarlosbaez somehow your fourth toot is displayed below, here, for me at least.
@quantenvogel - you showed a picture of some toots including, but not the now missing fourth toot, which was orphaned when I edited the third.
So, I think I was correct.
@johncarlosbaez ah ok, so I was fooled. Then it's indeed a problem!
@quantenvogel - Thanks. It's not visible after the third one for me. It still exists, so you may have just bumped into it randomly??? Confusing.
