As many may know, Wikia's tech team have blatantly botched something up, causing the videogallery tags to screw up.
The reason I've created this blog is to point something out.
Basically, don't go editing pages just to "fix" the videogallery tags when they're not broken - yes, they only "break" when the page is edited. Why? Think of it this way: the less pages with the temporary tag substitution (<gallery></gallery>), the less pages we'll have to re-edit when Wikia fix this problem.
Only edit pages to substitute the tags if they're already broken. Also, when editing a page for a non-tag-related purpose, and that page has a videogallery on it, do remember to substitute them before publishing.
