Tweet view missing quoted-tweet link?

[IBBoard]

I've got to investigate this more, but I wanted to record it in case others were seeing it.

In my timeline, I see a tweet quoting another tweet (e.g. https://twitter.com/codinghorror/status/1024736515916623872). If I double-click on the tweet then I should see the tweet with the link in place. That's been Corebird's behaviour for a while because single-tweet mode shows the unedited tweet.

What I sometimes see is the tweet text but no link. I do see the quoted tweet's images, if it had any, though.

As Corebird hasn't changed for a while then I'm guessing this is a Twitter data change, but need to confirm. Also, this only affects some quote tweets, and I've not found a pattern (e.g. https://twitter.com/GuitarMoog/status/1024738332197183488 quotes a text tweet and the link shows, but https://twitter.com/archillinks/status/1024736543553011712 quotes a tweet with an image and shows the link)

Ah, it's not consistent. Awesome.
I found a tweet where the link didn't show (https://twitter.com/SwiftOnSecurity/status/1025445601536700416), closed Corebird, opened a debug build so that I could dump the JSON, checked the tweet and it was fine.
I then closed the debug build, opened the standard build, and it now shows the link.
I'll continue debugging.
