A few days ago I noticed and posted (in support) a glitch because in external links (currently hidden/only visible from edit panels) TMDB links had been erroneously auto-directed to /tv/ID when movies are, on that site, /movie/ID in format...
THAT is resolved, BUT all TV shows need /tv/ added to their link because they will go to a dead page until /tv/ is specified. Tedious task, low priority, but while I don't know if there is a way to even SEE what shows have TMDB links across the site, at least people can be aware that currently they're glitchy because of the initial format's "oops forgot about movies" mishap.
