The game is very moddable, in fact I'm going to release my mod for making all non-zombie animals into friends, especially my wolf brothers and sisters, so you can all fight against the zombie hordes together. I've done this with A16 already and could release it now but would rather just wait for A17.
I know I just made a joke about it, but in all seriousness, expect bugs in A17E, is of course what you have to do. If you expect to be able to play the game, or accidentally end up expecting that so you get frustrated, then you're not playing A17E correctly. "Let's see how far I can get, and see which things are working currently and which things are broken and need reporting," is how you should approach it.
