No idea what to call this bug

I saw similar behavior in the spider that inspired me.
So it's not just this machine where this happens.

Did you check if you have duplicate blocks? That might cause weird movement.

Though it might have to do with the forward leaning legs, I know that causes builds to go forward, maybe it's constantly falling forward, but at the same time the speed makes it not fall down, kinda like segways work

Yea I do think it's something like that...

And I will check for duplicates right now

Edit:
No duplicates

I believe it's to do with the steering blocks working inconsistently. Similar issues has been found with wheels and other mechanical blocks.
It seems to be quite a major issue with a lot of designs.

Ohkay, I had only seen it happen once, but then I'm sure they're already on top of it

Thanks for the quick reply as always
