Strange bug.
https://mastodon.cloud/@eileenb/451324
this post showed up, on my timeline at mastodon.social. I don't follow the OP, no indication of a boost either visually on the timeline or at the item. It happened both on web and on tusky, so I assume it is not a temporary hiccup.
Might be a timing issue; I accidentally boosted that post instead of clicking reply then un-boosted it immediately.
(really like how the new UI asks for confirmation of boosts, but that wasn't the case yet when that happened)
commenting to add the context that I do follow @laanwj :)
Hahaha yes, that's an essential part of the picture
I've experienced the same issue with another tweet, displayed without the boost marker in both Tusky and on mastodon.social. Would the API have the boost info?
Same thing here : post from "Monsieur Zun" which I do not follow.

If this was a boost that got unboosted, that means it's issue #770, I think!
Closing as duplicate, see Gargron's comment on #2817.
