I've noticed this on a few different game wikis now, where none of the Game Details info is showing up anymore. No platform, developer, franchise, or genre info, its all blank. I don't know if its just not showing up for me, or if its for everyone, but I tried it in firefox and explorer with the same results. I've seen this also with characters and concepts disappearing too.
See Space Marine for an example of game details missing, and Far Cry 3 has no related characters info. I don't have a problem with filling the info back in, but it would be nice to know why this is happening so we don't have to keep doing it.
(Also its not letting me upload a screenshot either.)
