Hi there!

I'm trying to generate 10 random articles in Hebrew using this request:

https://he.wikipedia.org/w/api.php?format=xml&action=query&generator=random&grnlimit=10&grnnamespace=0&prop=extracts&exintro&explaintext

As you can see, I'd like to get their intro, but some of the articles' intro is empty in the API response, even though it's not empty in Wikipedia itself. 

I have tried to make the same request in English, and I the problem didn't happen.

This is the first time I encounter this weird problem after making this request in my App for over a year... Am I missing something? Is there any new information that I should add to the request or it's just a bug? 

Thanks!
