Flow does not seem to update links tables (tested with external links, and imagelinks). This means 2 things:
*Pages that link here, image usage, etc won't work
*When someone edits something else in the wiki (upload new version of a photo, delete a page [changing it to a redlink]), the page won't have its cache purged (I'm assuming that flow actually caches stuff, and that it hasn't totally re-implemented its own version of linkstables or something crazy like that).
