Save Our Ship is a mod for Rimworld extending the game after the construction of the spaceship with space maps and combat. The update for compatibility with 1.4 has not yet been released. Per the Steam Workshop page:

When will 1.4 be done?

No idea. We have almost no free time and it's a volunteer position only. These tasks are daunting for even the most serious advanced modder of rimworld with professional C# knowledge. If that's you, hop into our discord.
