For an "enhanced edition," it is awfully buggy. Why wasn't support continued?

Playing coop with a friend. Three most commonly occurring bugs.

1. When loading up a game to begin a session, the joining player's character is often stripped of all skill points and talents. It requires reloading.

2. Upon any load, the player joining shows health as 2/3 full while the hosting player shows full for those characters.

3. Enemies who, on their turn, just sit there and we have to wait random amounts of time for them to do nothing and end their turn. All sorts of battle glitches like this.

It feels more like a beta. This should be the ultimate finished version. Why aren't there more bugfixing patches?
