If I uninstall a mod, what happens to a craft that has parts from that mod?

[Blind Dead McJones]

I installed too many mods for my little old macbook to handle, so I wanna try deleting some. I'm starting with Procedural fairings. I know that I'll make the craft files unusable so I took out the PF parts and put in stock parts. But I already launched some probes that have parts from it in the transfer stage. I don't want to drop those stages now because I need the DeltaV, but I also wanna get this mod out.

By the way, this is because apparently having lots of mods uses more RAM and that apparently the increased RAM usage is why KSP is crashing more for me lately.

You basicly can't load it anymore, untill you reinstall that mod.

Crafts in flight will be deleted.

crafts in flight won't be loaded, you'll see a message when you load the game. Reinstalling the mod will let the game load them again. They may be deleted when the game autosaves later.

You could remove all the textures and whatever plugin pFairings uses. That would make all pFairings parts have no textures (no memory used there) and unable to use them. However, for a vessel in flight, you don't need to change the size or whatever, you just need the part (see: in Manley's Interstellar Quest, he removed the RT2 plugin but kept the parts and the craft loaded fine). I don't use pFairings, but I imagine the part you're currently using has a decouple module on the top - make sure that's in the cfg, remove all modules related to pFairings so you're left with basically a structural element in the shape of the fairing base. Once that's gone, you can safely delete the entire pFairings folder.

At least, I think that should work. Make a backup of your persistent.sfs and the pFairings folder first, to be safe.

Another way is to delete everything from pFairings except the part you're using and the plugin as well, though that would use more memory.

As it stands, if you remove pFairings entirely while that ship in orbit, it will be permanently removed from your savegame.

These probes all have that part in the transfer stage, which I can eject with a decoupler. The payload does not have PFairings parts. If I eject that and delete the debris, then it should be fine to uninstall the mod, right?

I'm almost 100% positively sure that might possibly work. Oh and you won't need to delete the debris as deleting the mod will make the part not be able to load so it'll be deleted for you. Just get your payload off that part and you're golden.

My first question is have you tried the Active Memory Management mod? There is also the Loading Textures Only as Required mod.

If you have either of those and still want to free up RAM, try deleting parts you don't use. (I.e if you have procedural parts you can delete all other fuel tanks).
