Disappearance, reappearance of thumbs-up

[grahamperrin]

Whilst at https://forums.macrumors.com/thread...-a-new-platform.1888744/page-23#post-21417928 I liked a variety of posts.

Then forward (probably via a 'more posts' link) to an earlier point in time https://forums.macrumors.com/thread...-a-new-platform.1888744/page-22#post-21417800

Then forward to https://forums.macrumors.com/thread...-a-new-platform.1888744/page-23#post-21417875 and at least one of the posts that I had liked no longer showed a thumbs-up. That memorable post: https://forums.macrumors.com/posts/21428077

I refrained from a second click on the thumb icon. Instead …

Workaround

I reloaded the third page https://forums.macrumors.com/thread...-a-new-platform.1888744/page-23#post-21417875

The missing thumbs-up reappeared.

Maybe related

Disorder and disorientation after replying at the foot of anything other than the last page

– although I don't recall posting any reply around the time of the disappearance of the thumbs up.

Postscript

It's possible that the missing thumbs up was first applied in a different window, maybe to https://forums.macrumors.com/thread...-a-new-platform.1888744/page-23#post-21417875

Whatever the origin: it seemed wrong for any step forward to result in disappearance.
