all of us have seen errors such as this:
:linmath(warning): Tried to invert singular LMatrix3.
:linmath(warning): Tried to invert singular LMatrix3.
:linmath(warning): Tried to invert singular LMatrix3.
:linmath(warning): Tried to invert singular LMatrix3.
:linmath(warning): Tried to invert singular LMatrix3.
:linmath(warning): Tried to invert singular LMatrix3.
or nodes being empty and cornucopia warning and errors. My question is what is the best way to find the source of the errors?
