Seriously, has support stopped for this game?

Yeah, as Tephra said, for some unkown reason Xbox has been left behind again and is missing the past couple of updates. The last official communication on the subject (that I’m aware of) is here, but that doesn’t exactly tell us much… The best guess right now is that it’s probably some sort of problem with getting certification for the updates (as you (probably) already know, all updates for either console have to be approved by Microsoft or Sony respectively) - presumably there is some reason why the patch cannot pass Microsoft’s certification (possibly just by being ‘low priority’ as a nearly dead game…). Unfortunately, all official communication on any topic has ceased since Dune came out, and Funcom is no longer even collecting bug reports, so it’s unlikely they are making any effort to push these updates through either. If it’s any consolation - depending on exactly which updates you did last receive, that may mean your game is actually in a better state than the rest of us, since the last couple of updates have been largely bad anyway (though it does mean you have missed out on the recent bug fixes as well).
