Is this bug invaild? I'll check back later.When programs crash I debug them.

Thanks. Ill look into it. Might be linux only

[Derailedzack]

I could do some testing on windows.I'm also a developer/programmer. I can confirm that it crashes on windows. I did update my drivers since I reported this bug.

[jmorton06]

Ah okay thanks for checking on windows too. Not sure why it’s crashing. I’ve seen this type of crash when it tries to load an old scene after the saving scene has updated and loads new things

Somehow the one I compiled broke so I had to recompile it. Here's the output from lldb(The clang debugger):

* thread #1, name = 'LumosEditor', stop reason = signal SIGSEGV: invalid address (fault address: 0x10)

   651        void loadValue(double & val)      { search(); val = itsIteratorStack.back().value().GetDouble(); ++itsIteratorStack.back(); }
   652        //! Loads a value from the current node - string overload

It also segfaults in sandbox so I wonder if there is a bug in the lumos library. LumosEditor and Sandbox crashes after loading the scene. I'll try to make a program to test the lumos library.This still occurs even with the newest branch.
