If you are moving from one or more equipment crafting mods over to DarkStar, your first step is to create a hard save (not a quick save) while standing just outside of the Lodge. This is the safest place to be. I cannot say what will happen when you uninstall another mod that affects armor and weapons, etc. Your gear may vanish off your person as soon as you load the game. This is to be expected, actually. You should expect to spawn naked with a new mod installed (DarkStar), and have to walk into the Basement of the lodge to craft a starting set of equipment with this new mod.
If you are high level, this should be relatively easy. Make sure you have plenty of crafting supplies on your person, or located safely in the lodge. Log out. Uninstall the other mod(s). Install this mod. Log in, and walk into the new room in the basement of the Lodge. Do some research, and craft spectacular gear.
It is also recommended, especially if you are lower level, that you have equipment that has NOT been modified by a mod ready and available to equip.
Never switch from one armor crafting mod to another without proper preparations. If you are on a planet with no atmosphere, your character may well get caught in an infinite death loop with no spacesuit on. So, park yourself in a safe space and be ready to do a lot of research and crafting when you load up DarkStar.
Trust me... it's worth the effort.
