I want to unsubscribe to a mod, but in doing so it causes the game to malfunction. Is there a way to fix that?

Solution 1:

Quite a lot of mods will modify your save too much to be fixed, and they'll often say so on their download page. There are certain inventory editors which can be used to save and edit your inventory - my best suggestion would be to use one of these to save your inventory and then create a new world after deleting the mod. Using /admin should allow you to skip through your pre-completed quests, and you can spawn some ship upgrade modules to get back your upgraded ship. This leaves the only obstacle as gaining crew members. If you follow this method, I strongly suggest you reinstall the game beforehand, or your universe will be the same, which will cause bugs.
