I didn't know axles actually had functioning rotation now. Last time I tried, they couldn't stay together to save their life. Even with multiples of them. That being said, Is that the hover bug making the legs rotate consistently forward without the user being able to move backwards? Because while cool, it is definitely limited in it's functionality. I've never been able to experiment with the hoverbug and don't recall ever getting it to work at all despite downloading working techs and completely replicating them block for block.
If axles and such are working more the way they should, I should give my ideas another go. I've been waiting for patch notes with something about them, but nothing popped up.
