I found what appears to be a bug with the NodeJS version of TiddlyWiki! Currently, as of TiddlyWiki 5.1.22, the static site generator in versions greater than 5.1.17 is linking to "missing" (non-existent) tiddlers, even though I've disabled that and the links do not appear within TiddlyWiki proper. I've made a discussion about this bug in the Google group.
