SMM ERROR
I cant seem to start Modded satisfactory which is weird Cause i played yesterday Without Problems and didnt add any new mods today/ Yesterday this is the error message:
This project requires the 'KLib' plugin, which has a missing dependency on the 'KPrivateCodeLib' plugin
Second Error Massage;
Plugin 'KLib' failed to load because module 'KLib' could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.
(my friend with the exact same mod can start modded satis without any Problem at all)

At this point, you'd be better starting again. Close SMM, then delete everything in:
%appdata%\ficsit
%appdata%\satisfactorymodmanager
%localappdata%\ficsit
%localappdata%\satisfactorymodmanager
and of course g:\SteamLibrary\steamapps\common\Satisfactory\FactoryGame\Mods
― this won't affect your saves, or your mod settings within the game.29 Replies

We need more information to help you. Before launching the game again, open the Mod Manager and use the "Generate debug info" option, then send the zip file produced here in this channel.
If you need to access older log files, see https://docs.ficsit.app/satisfactory-modding/latest/faq.html#Files_Logs
I cant seem to start Modded satisfactory now generally speaking without the Power Suit mod Installed which sis weird Cause i played yesterday Without Problems and i didnt add any modsWell obviously you removed a mod, so not really that weird. Removing mods will sometimes result in loading the save appearing to hang, as the game tries to log all the now-missing elements. Also, the Power Suit mod was never updated to work with v1.0. So you're either running an old game version (which is unsupported), or you're trying to load a save from an old version in a v1.0 game, which is going to run into a lot of problems with mods that don't support v1.0.
I am playing in the newest Version of satisfactory and i am Not able to start the Game at all with the Same Error Message appering and the modded world was created like 3 days Back
Well, like I said, Power Suit isn't compatible with the current versions of the game, so... that's probably a not-insignificant part of your problem.
In any case, please provide your debug logs as instructed here: https://discord.com/channels/555424930502541343/1369020746633969755/1369025619823825018 (Note: you mention an error message, but you haven't actually said what that error message is).
If the game is crashing, please make sure to provide an error log immediately after it crashes. A debug log generated after running the game without it crashing, will not be of much use.
Ok i dont what happend but the Error Massage which i Had pasted in Is Just gone
This IS the Error Massage:
This project requires the 'KLib' plugin, which has a missing dependency on the 'KPrivateCodeLib' plugin.
And If i click yes this one comes:
Plugin 'KLib' failed to load because module 'KLib' could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.
I will Provide the debug logs soon and also (This IS my mistake) i pasted in the wrong Text so this has nothing do to with the Power suit Mod IT IS Just an Problem i have Generally with trying to start modded satisfactory over the SMM lauchner

None of the mods you have enabled require KLib. Likely, something has been left behind from an old mod. Open SMM, disable mods (big buttons on the top-left), close SMM, open
g:\SteamLibrary\steamapps\common\Satisfactory\FactoryGame\Mods
and delete anything in there, open SMM, re-enable mods.

New Error Message:
Plugin 'FileSystemLibrary' failed to load because module 'FileSystemLibrary' could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.
(mod istalled rigth now : Refined Power and Ficsit Farming
That's because you didn't do what I asked you to, and just wiped SMM entirely instead. That profile has no mods loaded in it at all, though obviously (again), there are mod files remaining in the Satisfactory\FactoryGames\Mods directory.
I wiped the g:\SteamLibrary\steamapps\common\Satisfactory\FactoryGame\Mods Completly
Please screenshot that directory.
it just regens the mods
Yes, that is the point. But that profile you're loading right now in SMM has no mods in it.
as soon as i reactivate the mods it just Reinstalles the mods

Yes, again, that is the point. To remove the old mods that were calling the unused dependencies (KLib ― since none of the mods in your profile use KLib), and then load only the mods you need. However, given that you current SMM profile, again, has no mods in it, there should be no mods in that directory right now.
i dont know what i did but now it only generrates one file called new-lock (new Being the name of the Profile)
now i can start satis without any mod and without any error Message
I tried to install Refined Power and as soon as i launched new error Message came
Plugin 'RefinedPower' failed to load because module 'RefinedPower' could not be found. Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project.
