[22:48:21] <ticky>	 Right, I investigated again and the issue is that some extensions expect to be able to load "autoload.php" from their "vendor" directory, and not the mediawiki "vendor" directory, any good fix for that?
[22:55:00] <bawolff>	 Any extension manually loading autoload.php should be considered broken
[22:55:12] <bawolff>	 So write an angry letter to its developer ;)
[22:55:50] <bawolff>	 Generally speaking, extensions are supposed to specify load_composer_autoload in their extension.json to have mediawiki take care of it
