Well, I don't know if you happen to have any old $0 Vanguard-to-Merchantman CCUs lying around as apparently those were never removed when Turbulent activated their "$0 CCU removal script".
You see; I still have a $10 Merchantman-to-Hercules CCU in my Hangar. I'd be perfectly fine to gift it to you as I have another in my BuyBack. That would give you the option to upgrade that Terrapin in the Explorer pack to a Warden at some point and from there to a C2. Just let me know as I'm just offering options.
