Yeah yeah yeah, he's fixing all that.
1. The models are meant to be joint-less to fit the Blockhead theme.
2. Console errors will soon be fixed, in the next update.
3. In the next big update, there will be an option to toggle zombie-like intelligence or have a newer, smarter AI system.
4. And in the next update, these will be the "default" coloring, and if you hit Re-Color vehicle, it will become that color.
