No surprise people are still whining about the game not being as far along as they want it to be, thinking it's been a whole team working on it since the start. The dev team got bigger over time and was able to do more, they also had to learn different things, it takes time to model and code everything and then to make the animations with dealing with the mocap actors' schedules and having access to what they needed, while having a team dedicated to the sandbox mode to give something for people to mess around with during the early stages. Not to mention it has gone through reworks to the world and story and such just like a big studio would have, like look at the original Halo and what Bungie thought it was going to be early on.
The devs are actively working on the game, they share development progress, especially on the discord server there's a monthly progress report. The fishing village demo that gets touted as the holy grail of where the game was going have obviously forgotten what was said about it, which was that it was a demo and very likely would change, not to mention it was on the old map which the devs did not like, so as they got better they made a better world. The world is being filled in so it actually has locations, characters are getting updates related to those new locations, the story is slowly being worked on. As for bugs, if you expected a game in active development that is being shared for everyone to play to not have bugs, then when you get a bug it's on you, but you report it so the devs can actually do something about it. At least there's something here, be happy for that.
