Node War Issue (Crescent Shrine) [NA]

So my guild and I went to Crescent Shrine so we could place a fort and participate in the node war. We placed the fort, all the barricades, and everything else. Once the node wars began, we were teleported back to Sand Grain Bazaar and got the message that we weren't participating in the node war. When we arrived at our fort (still it was still there) we stopped getting that message, and even now after the Node War period for Crescent Shrine (today) is over, our fort is still here. Is this a bug? Did we mess up? Help!
