Update on my vehicle (which I sense may very well be on Dionysos Leader):
My CA just shared an update. The vehicle is now expected in Port Hueneme on 2/23 (or 10 days later than expected).
In the latest update, the prior vessel - Serenity Ace - is still displayed as the shipping vessel although Serenity Ace continues to make progress towards Tema, Ghana.
The exact vessel where my car may be still remains a mystery.
