[Debug mode]loading mission get an error

f:torque 3d pro 1.1/engine/source/core/util/refbase.h(192) :
Fatal - Decrementing a reference with refcount 0!

/// Decrements the reference count.
   void decRefCount()
   {
      AssertFatal(mRefCount, "Decrementing a reference with refcount 0!");
      if(!--mRefCount)
         destroySelf();
   }

I can get in mission in release mode ,but I get a crash under debug.
Anyone get this crash in debugging ?How can I figure out it?
