The fact that it's free doesn't mean no complaints are valid.
That being said, I think a small update with decent pacing is fine. It was never gonna be a big update. The hiatus wasn't them doing a giant update. The hiatus was cbob's mental health stopping him from getting ANY work done. So it was always gonna be an update the size of a regular update or less.
If you expected a mega update to make up for lost time, you set yourself up for dissappointment. I'd rather they take the time to do small amounts of quality work instead of rush out a large amount of garbage. Because in a year or 2 when we have the full game, it will be a great full game. Instead of demanding a large about of content that would be rushed.
