Just tried to dock a sprint on the old med neb, when i hit dock in in the travel screen it did not show the med neb. I own both ships and I even added myself to the crew list and made myself Pilot and commander. Was just wondering if it was a bug or never got implemented when they were added.

The older med nebs, made before the unlocking of the DCs, retain their stats from before. This means no docking bay, but slightly more weaponry. If you want one with a docking bay, best bet is to sell your 'rare' med neb for insane amounts then buy a new one for slightly less insane amounts.

I thought they had added a docking bay to it. There is a room named Docking Bay, Guess thats due to the floor plan for the old and new is the same.

Likely, now that they changed the way rooms work with entities.
