I've got a Constellation Phoenix which came with a Lynx Rover. I'm not 100% sure that when I upgraded to the Hammerhead if I lost my Ursa in that upgrade or if I still have it. It's listed in the Vehicle Spawn menu but that might just be a place holder for the Lynx.
I also applied for a Kraken. Not sure if CIG is doing this to give a few to players or if this is a metric to see how many to sell. If it's an actually lottery than I'm happy, everyone had a fair chance. If this is a sale then I'll be justifiably upset because I'm not some IT Tech making a six figure salary that has a ton of extra money to sink into ships. I've got enough bills and living expenses to keep my savings each month to a minimum.
