The problem was that the innerwiki template included the tiddler $:/plugins/tiddlywiki/railroad, which was omitted from the wiki. Unexpectedly, missing tiddlers were rendered by the jsontiddler widget as an empty object {}. The fix is to always include the title when the tiddler is missing.
Also cleaned up the template to remove unneeded tiddlers
