Yes, according to Jain tradition, Drishtivada, the 12th Anga, remained available in the 5th Ara for about 1,000 years and was then lost.

A small clarification:

• Shvetambar tradition generally holds that the Jain Agamas were gradually lost over time, and Drishtivada was the last one to disappear.
• Digambar tradition also accepts that the original full Agam knowledge is no longer available in its complete form.

So the basic idea is correct: Drishtivada survived into the 5th Ara for some time, and then it became unavailable.
