When you undock with the Spiral, it has 6 cargo spaces, everything “normal”, like a regular frigate.
But, when you undock with the Endeavour, it has 8 cargo spaces, 6 from the regular frigates and +2 from the “premium” (like the Thar’Ga and Tai’kin, and maybe the Gargoyle and the Dart, but since i don’t have them… i can’t check it)
If the Spiral had 5 cargo spaces, i could undertand it would be considered as an interceptor (3 spaces +2 from premium).
So… what’s the problem here? Are both considered as premium ships? or only Endeavour does?
P.D.: If someone wants or knows how to report it in a proper way… feel free to do it.
