Someone made an RSR in a new product this year?

Okay. That's legitimately ridiculous. LOL. But thankfully we know how to deal with them quickly. :) ("Them"..ambiguous reference fault.... oops....deal with the RSR's, I mean. Not the vendor who created them.)

It's actually more than one person.  It is several people.  Not to mention the fact that a ton of DAZ products still have them.  Just because DAZ repackaged all of their content sans installers doesn't mean that they would actually update anything.  There is a lot of DAZ Gen 4 content that is still for sale both here and elsewhere that still have .rsr files instead of .png files.  What is worse is all of the vendors that still tell their Mac customers that they need Macconverter to use their product (And they still do that with new products in Nov. 2014).  The vendors obviously have no clue as to what the product actually does.  (For those of you who don't know - it was a product that converted Poser 3 content to something Poser 4 could read.  It was also an OS9 product.  And the website for the product went dark about 13 years ago.  And you haven't been able to buy a Mac that runs OS9 in about a decade.) 

There is no telling how many sales that particular stupidity has cost vendors over the years, just because they couldn't be bothered to find out what the product actually was.
