When --content-disposition changes the file type, the new file is placed in the directory wget2 was called from.
when I call wget2 from a directory, I.E. /home/example/ all of the files that were named using the content disposition headers(pdfs, pptx, etc) are placed in that directory. They do not appear in the directory of the page they belong on, or the directory specified by the output flag. This leads the convert links to fail as well.
