Duplicate datablocks

I have made some code modifications to TGA 1.7.1 and noticed some errors in my console.log file. I went back to an original install and noticed the errors are there when running vanilla installs.


There are several errors (actually warnings) related to duplicate datablocks. I have listed a few below. Should I worry about these erros? I know I will as I am looking for a clean console.log to tell when I have generated some errors.

Thoughts?
