I posted about this model bug in the regular GC2 bug forum before I realized that there was a separate forum for Dark Avatar, so I apologize for the repeat.
The third large hull model for the Altarian/Korx ship style, does not seem to load properly into Dark Avatar. The thumbnail shows a blank, and when you click on the thumbnail, no hull appears in the ship design window. Furthermore, it does not allow you to place any components. I posted slightly more detail about the problem in my post on the regular GC2 forum.
I think that Dark Avatar looks fantastic so far, and I am looking forward to the final version.
