Lol Dubs you're trying to say that "forever" doesn't mean "permanent"??
Haha, I know what you mean but I think its understandable how it could get confusing to someone
To OP... the foreverroot hack is not permanent, its a quick script edit that lets root carry over through the update process, but some of the more recent leaks suggest Moto is trying to block that from working as well. Luckily, it works just fine with 5.5.893. And the script would not permanently root your phone, you could always unroot just as easily as you rooted, or restore to stock, or whatever.
More importantly though, you say that you updated but still have root access, although only Titanium isn't working? I would go to settings>applications>manage apps>all, and clear cache and data for superuser, then reboot. Once booted, try Titanium and see if it will request SU permissions like normal so you can allow it. Yes you'll have to allow for all your root programs again, but that should only take a minute really.
