Poser File Organizer converts those pesky RSR's. I know because I've converted a TON of them. It also fixes path issues. Converts Matposes to mat files. Remove detached nodes. Will restructure shaders, in fact. And about a million other things. Quite handy. 

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.)
