Issue with Kopernicus and Real Solar System

[ewqqwa]

I have been trying to install Real Solar System, Realism Overhaul and RP-1 with CKAN since I felt like I needed to take a break from normal KSP but I ran into a problem. I know there are more topics about this but I've tried every single one and I have also redownloaded the mods many times but without any success. I am playing on version 1.12.3.

When the game finishes loading, a warning pops up saying

Kopernicus was unable to load the custom planetary system due to an exception in the loading process. Loading your saved game is NOT recommended, because the missing planets could corrupt it and delete your progress. Please contact the planet pack author or the Kopernicus team and send them a valid bug report, including your KSP.log, your Module.Manager.ConfigCache file and the folder Logs/Kopernicus/ from your KSP root directory.

Don't install mods in the Steam copy of KSP- especially a modpack as large as RO/RP-1. Steam will almost inevitably corrupt something resulting in a weird failure of some sort like you're getting. The simplest solution is to not put mods in the Steam copy of KSP:

1. Uninstall all mods from KSP so that GameData contains only Squad and SquadExpansion (if you have either/both DLCs) and nothing else.
2. Right click KSP in Steam library > browse local files.
3. Copy KSP/saves/<your save name> and paste that on the desktop.
4. If you used CKAN to install your mods (and you should!), click File > export modpack and save that to your desktop too. Screenshot your GameData folder with mods installed (even if you use CKAN) so you can check that you’ve reinstalled them all later.
5. Uninstall all mods from KSP.
6. Right click KSP in Steam library > properties, disable Steam cloud.
7. Completely uninstall KSP through Steam.
8. Reinstall KSP through Steam, right click > Properties > local files > verify integrity of game files. If you want to play a version other than the current release (1.12.4), pick that version in the Betas tab and verify the files once Steam has installed that version.
9. Run KSP and make sure it loads properly without mods.
10. Browse local files again, then go up one level (to Steam/steamapps/common) and copy the Kerbal Space Program directory, then paste it where you want to keep it- make sure it’s outside Steam’s folders so it can’t meddle with it in future.
11. Rename the KSP folder so you know what mods you’re using in it (e.g. 1.10.1 RO/RP-1, 1.12.3 JNSQ), then add this new copy to CKAN and use the modpack created in step 3 to reinstall all your mods; or reinstall them by hand if you don’t use CKAN. Double-check that all files and folders you had in GameData before uninstalling/reinstalling everything are there again, if not then you’re probably missing some mods.
12. Move your saves from your desktop into your new KSP copy’s saves folder, run KSP, load save. A warning about vessels having missing parts is usually because a mod is missing or wasn’t installed correctly.

You can make as many copies of KSP as you want, have several copies on different versions and with different sets of mods in each- CKAN makes this much easier to keep track of, but it’s still possible to do it all yourself.

Use the RP-1 express install option on CKAN as that will install everything you need for RO/RP-1. A few options are available with different texture resolutions and extra visual stuff like a realistic Cape Canaveral, but you can delete these extras afterwards if you don't want them.

Thank you a lot, it worked!
