Exception: NullReferenceException

[Admiral Fluffy]

So I was just playing KSP when the computer crashed.  I rebooted it, and when I tried to load the save that I was playing on, this came up:

[Exception: NullReferenceException: Object reference not set to an instance of an object] and the save didn't load. The other ones do.

This is what the files look like for the save. 

I don't think any of these should affect it, but I am going to put them here just in case they do.

Mod list:

List in text:

ClickThroughBlocker, Harmony, ToolbarControl, AvaliSpaceProgram, BetterTimeWarp, Chatterer, ExplodiumBreathingEngines, FinalFrontier, GEP, KerbalKonstructs, Kopernicus, KSPCommunityFixes, ModularFlightIntergrator, ModuleManager-4.2.1, OPM, RandomMainMenuBodies, Reentry_Particle_Effect_Renewed-1.9.1.1, Scatterer, ScattererAtmosphereCache, Sigma, SoundtrackEditorForked, SpaceTuxLibrary, Squad, SquadExpansion, StockWaterfall Effects, Waterfall, WildBlueIndustries.

Help would be greatly appreciated. Thanks!

Do you know where your logs are?

Did you try to use a BACKUP save yet?

There is a folder in the save directory with above title. Find the most recent time stamp and rename it to .sfs extension.

Copy & Paste into Save directory & try to load it.

If that doesn't work it will require a bit if troubleshooting (and still might not work) to determine which mod is conflicting.

Thay require looking for errors in the log. Then you find the appropriate subforum and request help There.

 

Have you installed any new mods recently?

Updated any?

You can go into Ckan and reload past versions of recently updated mods to see of that may have been at play.

Familiar with file sharing like Google drive or Drop Box? Share the file player.log and I bet somebody with more know how than me will take interest.

It generally a good idea to share the file with a request bc it gets the tech wizards interested.

And is required to diagnose any serious issues.
