I would use it though, I've seen quite a few richard moves regarding loading and saving stuff.
The addon won't even stop that.
All it is is re-making the default bricks by renaming them into their own tab.
ALL YOU HAVE TO DO IS DOWNLOAD THEM
As in, say person 1 loads a build with the 'fix', and person 2 sees in the brick tab this giant category named "NEW DEFAULT BRICKS", they're going to go look for those bricks, download them, save your build, and boom.
The nice little 'fix' did absolutely nothing.
OT:
I hope he is revoked, as this has been stated NOT to do many, many, many times.
