The Cabal Philippines game Client just recently got updated and the good news was that the Nation War patch now included. It fixes also the crafting bug which was reported by the Cabalistas few weeks ago.

The Nation Wars
You can only join the Nation Wars after you complete the Nation Quest, which you can take only upon reaching level 95. After you’ve chosen either Capella or Procyon, you can take part in the daily struggle for National dominance. Only the first 100 heroes from each Nation can enter Tierra Gloriosa, the War Server. The two Nations will battle over the outposts that are being controlled by massively powerful guardians. The Nation that takes control of the opposing Nation’s capitol will control the battlefield.
The war will go on day after day, however due to the agreement that Capella and Procyon entered with Sirius, the war can only last for one hour (1hr) per day. Entry to the Nation War costs 1,000,000 Alz, which will not be refunded regardless of whether you quit or get disconnected. The lobby is open for half an hour before the Nation War so that the members of each Nation will have time to plan their strategies, purchase items from the Grocer, leave items with the Agent of Port Services, and recover from their previous battles. While only 250 players can enter the lobbies, only 100 from each Nation can take part in the Nation War.
There are two kinds of Nation Wars: Personal and Mission.
Personal Nation Wars–is a general battle where players receive rewards based on the number of outposts they overtake and enemies they killed. It takes place once a day from Sunday through Friday from 18:00 to 20:00 hours.
Mission Nation Wars–after a Mission Nation War, all members of the Nation that won will receive spoils of war. Mission Nation Wars take place once every Saturday from 18:00 to 20:00 hours and on special events.
