**Steps to replicate the issue**
Visit https://meta.wikimedia.org/wiki/the Special:GlobalContributions/Leaderbot page for a bot account.
**What happens?**
Only contributions which the `Leaderbot` account made on testwiki are displayed.Edits made by bot accounts on local wikis do not appear to be shown. Examples:
This behaviour occurs consistently for me - whenever I've visited Special:GlobalContributions for this * https://meta.wikimedia.org/wiki/Special:GlobalContributions/Cewbot shows "No results matching the query", but the account has recent contributions on [[https://en.wikipedia.org/wiki/Special:Contributions/Cewbot|enwiki]], [[https://zh.wikipedia.org/wiki/Special:%E7%94%A8%E6%88%B7%E8%B4%A1%E7%8C%AE/Cewbot|zhwiki]] & [[https://commons.wikimedia.org/wiki/Special:Contributions/Cewbot|commonswiki]], among others.
* https://meta.wikimedia.org/wiki/Special:GlobalContributions/'zinbot shows "No results matching the query", but the account has recent contributions on [[https://en.wikipedia.org/wiki/Special:Contributions/'zinbot|enwiki]].
* https://meta.wikimedia.org/wiki/Special:GlobalContributions/SodiumBot shows "No results matching the query", but the account has recent contributions on [[https://bn.wikisource.org/wiki/%E0%A6%AC%E0%A6%BF%E0%A6%B6%E0%A7%87%E0%A6%B7:%E0%A6%85%E0%A6%AC%E0%A6%A6%E0%A6%BE%E0%A6%A8/SodiumBot|bnwikisource]], [[https://fr.wikisource.org/wiki/Sp%C3%A9cial:Contributions/SodiumBot|frwikisource]] & [[https://en.wikisource.org/wiki/Special:Contributions/SodiumBot|enwikisource]], among others.
For a reason I'm not sure about, https://meta.wikimedia.org/wiki/Special:GlobalContributions/Leaderbot also doesn't display any recent edits made from that account, the testwiki**except** for edits have always been the only cmade on [[https://test.wikipedia.org/wiki/Special:Contributions that are returned/Leaderbot|testwiki]] in December 2024.
**What should have happened instead?**
The account'ss' recent contributions from all wikis should have beenbe displayed.
**Software version**
1.44.0-wmf.18
**Other information/Notes**
This may be being caused by a known issue (T384717 comes immediately to mind), but I'm reporting it just in case it's caused by a problem that's not yet known about.
