Thanks for your patience! I finally found the time to update for Voyagers and get everything up to spec:

It took a few dozen hours, but all that is added is FREE for you - if you can, please donate (or join the Patreon to access some extra features), especially if you wish to OBLIGATE me to get this done faster next time! It's taken me so long as I am under financial pressure myself and must prioritise work. I understand I am not the only one, so don't feel pressure to donate. Everything is done with love <3

- Corvette support added

- Ship customisation/fabricated ships now save with the ship, same for multitools

NOTE: There is still a bug for some (or maybe all) xbox/ms store users. Please watch this space, we are working on a fix.
NOTE: WinStore issue identified. Some people might not be able to save changes to their save game and it will become corrupted. There are instructions in app on what to do if this happens. This has been identified in NomNom. IO code, which is handled by a third party and if/when they release a fix, it will arrive in NMSC as well (see NomNom Save Game Editor). This issue only affects some users.
