Where have all the Classic Reward flights gone?

Last year I was able to pretty easily book Classic Reward flights. Lots of flights available.

Today, I can't find any routes available from Melbourne to Japan and Vietnam using many different dates. Not only that, the search functionality has been removed so I have to search for exact dates as opposed to a date range.

Details:

- 120k points,

- Depart/return: anytime in January

- Depart from: Melbourne

- To: Vietnam/Japan

Is anyone else having trouble?
