YAMLMerge error

Hi,

we're currently having problem where we cannot merge scene because YAML merge always return error when trying to merge the scene and here is the error returned from terminal

UnityYAMLMerge(36505,0x70000f3cc000) malloc: *** mach_vm_map(size=2305843009213693952) failed (error code=3)

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

libc++abi.dylib: terminating with uncaught exception of type std::bad_alloc: std::bad_alloc

we're currently running Unity 2017.4.8 in Mac and our scene currently are at 13.5MB size . we've tried to use another unity version's YAMLmerge without success. do anyone have idea what happened?

 

Create new component, destroy component in scene sometime broke and create null, artifact invisible objects in scene.

Copy all of your GameObject from old broken scene then paste it into a new scene. It might work.
