This tool is ok (unless you can't pack files with WinZIP). Never used it, but was forced to do that. And found very serious issue here - packer don't automatically catches *.tbn and Netrisca related files at all! So you map will be without thumbnail and will spam error messages in console about missing textures and *.txt files. I don't wait for it to be fixed (nothing can be fixed in SSR since 04.2015), but maybe, who knows:) Also why packer don't remember game path? Searching the game inside Steam folders jungle is deadly annoying
