Repairing craft with modded parts

[Adelaar]

Hi,

I have a few ships in my inventories which are broken now that I've purchased breaking ground, especially ships using older KAS parts. They are failing to load, so I can't remove the parts to repair the craft involved. Anyone with an idea how I can save these craft?

@Adelaar Does the game complain about 'missing part modules' when you try to load the craft? In that case, you can still load them - the message is just saying 'this craft was built with x mod installed, but it's not installed anymore and things might be broken'.

If it says there are missing parts, then it'll be a bit trickier. You may have to edit the .craft files for the affected craft, and remove and/or replace the parts manually.

It actually fails to load... So I get a message that a part is missing and then it reports it can't load in the craft at all.

Hmm. You said that some craft have old KAS parts. Some of the old KAS parts were replaced with very similar versions when the mod was updated to 1.0, which means that it's probably possible to replace them by editing the .craft file. However, other old KAS parts were simply removed, with no replacement. Crafts with those parts may be unsalvageable, unfortunately. I'd recommend asking in the KAS thread about what parts were removed/replaced, and if it's possible to edit the .craft to replace any of them.

I use KSP Mod Admin to verify/edit craft files .. Been a while since I used it with craft files, tho... IIRC, it tells you what parts come from what mod.. at least when the mods are installed... ie you can find parts in a craft from a mod you want to uninstall... find the parts, and delete them from the craft file, *then* you can remove the mod...

I'd probably just delete the affected craft files and rebuild them from scratch, but if it's absolutely critical This describes how to get Legacy Parts back which should let you load the craft files.

Even if you reinstall the legacy parts, I'd only do keep them around until you have repaired your craft files and then remove them again. Legacy parts aren't supported and will quit working completely at somepoint, so there is no point in trying to use them.

If they are just things like winches & connectors on the outside of the craft, rather than critical structural components, its pretty easy to edit the craft files & delete them.  I had a few I've had to that too.  Use <Control-F> to find the bad part names & delete both the part & the links to it. 

For example, on an old spaceplane of mine, I had some connector ports on the engine nacelles for refueling on the ground.  If those were from the old KAS version, I would go in and search for "KAS"   The first thing that pops up is this line (in bold)

I would delete that line (which is where the bad part is attached too) & then keep searching for the actual bad part, which turns up:

This you have to find the entire part section from "Part" to the closing "}"

If you only have a few, it's not too bad.  If you have a bunch of parts, you might be better starting from scratch.  Another option if you still have an older version of KSP saved, you can go to it, take off the bad parts, save the craft & bring the fixed craft file over.

Thanks Cavscout, I'll try that...
