Sorry about that! There were a few builds that went out over the weekend that might give you some trouble when you try to update. Would you mind updating by hand, please? This is fixed in the later builds which can be found
here.
Schimmi, these builds are the exact same as the ones you'd find via the automatic updater and this particular issue should be separate from anything you'd find in OmniFocus. If you're experiencing trouble with project view, would you mind sending us a bug report (via the help menu in OF) so that we might get to the bottom of this, please?
Again, I'm sorry for the trouble. Thanks, guys!
