FCAS causer pays tests failing. Data missing from nemweb?

[mdavis-xyz]

I'm trying to run the unit tests.
Test tests.test_data_fetch_methods.TestCustomTables.test_works_on_recent_data is failing. It's returning no data.

It's trying to download files like:

https://www.nemweb.com.au/Reports/Current/Causer_Pays/FCAS_202602200025.zip

And getting a 404.

There's an empty folder at https://www.nemweb.com.au/Reports/Current/Causer_Pays/

The adjacent folders are called:

Causer_Pays
Causer_Pays_Elements
Causer_Pays_Rslcpf
Causer_Pays_Scada

I suspect AEMO changed the structure of nemweb, and we need to modify nemosis accordingly.

Although only the Elements folder has data.

I've never used this dataset. Is Elements all we need?
