Something Broke PartTools

[TiktaalikDreaming]

I honestly don't know if this was due to a Windows (10, home) update or something else on my system, but I'm keen to know if it happened to anyone else.  My Unity5.4.0p4, which hasn't been updated, suddenly gives me "NullReferenceException:" relating to KSP Part Tools, on all my projects.  It's across all the projects, so I haven't done something daft to the part tools files.  The KSP install referenced is still where it was.  But not having anything referenced wouldn't manage to do this.

Full error;

And it's just the one computer.  My Unity projects are all inside my dropbox sync file set, and I opened it on my laptop, and it's fine.

Rebooted PC, still an issue.  It may be Unity reinstall time.  Just to check dependencies etc.

If it's not too late, have you installed any mods that are likely to have empty example cfg in them?  Unlikely you have as a mod maker,but worth a mention, part tools hates empty and example cfg's  tweakscale has a couple that if left in will break part tools ( there are others but offhand I can't recall them) and usually end up with the part tools editor window stuck on screen constantly but inactive, removing the offending problem file usually fixes part tools after a unity restart

That would be the sort of thing that might explain it.  :-/

Just uninstalled Unity.

I'll test the reinstall Unity in ~380MB time. Assuming that doesn't work, I'll go looking for pesky null configs.

Twas an empty config file in CommunityResourcePack, AsteroidScannerSetup.cfg

Thanks heaps @SpannerMonkey(smce)

I've had this problem as well with Unity ... the cause was having my projects in Dropbox, at one point it locked a file for synching while Unity tried to write it. If you don't do already: always disable autosync while at work.

Oh yeah.  Dropbox and Unity hate each other.  Not just the Unity project lock file, but the baulking when writing out parts due to file locks on temp files and so on.  So, yes, I disable the sync when actually using Unity.  Pretty sure I've come across all the variations of Unity and Dropbox fighting from all the times I've forgotten to disable syncing.  :-)
