wow, for over a year, from what you say there are still so many bugs?
There are so many bugs BECAUSE they have been adding systems for over a year. The game has become very complex. Plus, as I said a lot of the work is finishing up and polishing systems that were implemented before the feature lock.
For example: faatal added the new pathing system. Now he is working to make sure it works in every instance of the game. Recently he was working on Blood Moon nights. The Blood Moon hordes were not placing the zombies on his new pathing grid so they would fall off the world. That is an important job to finish up before the community gets it.
Another example: faatal added the new vehicles and their physics. But there are a lot of smaller details involving the vehicles that also need to get done in support of the models existing in the game and being drivable. Nailing down the rules of exiting the vehicle was just one recent task that he was working on.
Another example: Randomly Generated Maps technically can be made and played in but there are problems with the process that Kinyajuu is working through and it would be confusing and frustrating to the average user to try and get a random map loaded and more frustrating to play it since it is still being worked on.
Another example: Attributes, skills, and perks were added months ago but just adding the names and the structure to the UI is not enough. Madmole has been working these past two weeks hooking everything up so players actually get the benefits and the descriptions are correct. Until two weeks ago the Intellect attribute was missing completely and no matter how long you played you could only ever craft brown level gear. There was no crafting progression at all.
So yes there is lots of work to be done and yes some of it could be done after A17e is released but would often necessitate wiping and starting fresh on the new build. For the average gamer that causes game fatigue and they get burned out on A17 before it even reaches stable.
So...yes there are enough bugs and tasks so that TFP could work on them into next year if they wanted to get them all before releasing. But I don’t think they will do that. They will get it to an acceptable level in the minds of the owners and then it will be released and they will keep working on all those bugs while we have the experimental version.
As I said, it could be released today in its current state if TFP wanted to do that so just because there is lots to do it doesn’t automatically mean 2019.
All we have from Rick is his statement a few weeks ago that releasing before the end of September was unrealistic.
