NullReferenceException (1.1.2 64-bit)

[Raideur Ng]

Kerbal Space Program - 1.1.2.1260 (WindowsPlayer)

Problem:

Unable to enter KSC buildings or main menu.

 

Mods Installed:

Chatterer_v0.9.7

RCSBuildAid_v0.7.7

KerbalAlarmClock_3.6.1.0

 

I recently removed several mods including KerbalAtomics, CryoTanks,Stock Visual Enhancement, Scatterer, etc trying to fix this issue.

This occurs when I try to go into any of those menus:

[EXC 15:23:56.458] NullReferenceException: Object reference not set to an instance of an object

Same as above, I have had a career game going without changing mods for a log time, suddenly I can't enter / exit buildings.

I believe what's going on is that there's a part test contract in your saves (either offered or previously completed) which refers to a part that no longer exists.  I got bit by this one just now, when some deprecated parts (which I had tested for some contracts) were removed from a mod I use, which caused the contract system to choke.  I know @Arsonide mentioned looking into this bug in this thread, in the context of offered contracts with removed parts, but it looks like the bug also strikes in KSP 1.1.3, when there are completed contracts with removed parts.

My solution was to dig into the save file and snip out any CONTRACT_FINISHED blocks of PartTest type which had a part that didn't exist anymore.
