1. Yeah, the passive battle mode is kinda buggy right now, just don't enable it yet
2. https://trello.com/b/y6wrjnbj/growthrpg-v054 (changelog) scroll to the 'Body parts to add' section. From what you can see, there's no guarantee that there will be a human part added in the near future.
If you have any more questions, I'll help you if possible. ^^
