This was kind of ridiculous. Is there even a point in releasing an update like this?
I guess it confirms you didn't do literally nothing in the past month or whatever, but only just barely. And it confirms you did nearly nothing. Combine that with the disappointment people are going to feel once they play it... I can't imagine releasing nothing is worse. Give a lil update notice explaining what happened, and at least you avoid the worst of the crash from "Oh nice a new release! oh wait it's already over wtf?"
On top of all that, folks that are already invested will be mostly willing to cut you a break if shit happens, and by omitting the update it's real clear that's what they're doing. Releasing an update like this gives off more the feeling the 'agreement' has been fulfilled... just with utter crap. It's the "oops I forgot, lemme get you next time" vs the "oh uh right yeah, here's a quarter, we're good yeah?" thing.
