Where are the term tokens gone?
Enabling the Entity_Token sub module does help with this issue, however, you need to add a "Term Reference" type field to any of your content types in order to see your taxonomy vocabulary be listed as one of the replacement tokens.
In my case, I had enabled the entity_tokens module but I was still not able to see my vocabulary as one of the replacement tokens.  Then I added a new field to my "basic page" content type.  The field type I added was "term reference" and I selected my custom vocabulary as its default vocabulary.  This resolved my issue.
