Views not getting saved after upgrade to 6.x-2.16

I am working on a site that recently had the views module upgraded from 6.x-2.1 directly to 6.x-2.16. Everything seemed fine and all views displayed correctly. We have now discovered that we cannot save any new views. When we create a view and click save, the message says the view is saved, but a page not found error is displayed when it tires to reload the page and the view does not show up in the list of views. I read an another issue for a different version number with the same problem and one of the comments in that issue reads "Here is the reason for this problem: 6012 is missed in 6.x-2.x" http://drupal.org/node/1127872#comment-4516196. I checked on my updates.php page and it does list 6011 and 6013, but there is no 6012 in the list. Is that the problem? If so, what do we need to do to get that update? We do have a database backup from before the update, but it is from a month ago before views was upgraded and content has been added since.
