I can confirm. I had the same thing happen to me. I filmed it for comedic effect. It was like a bad acid trip. I even fired the hull guns just to see what would happen.
Sky/ground/sky/ground/sky/ground, etc. while the treads were screaming at high speed.
With me, I was climbing the hill forward and I think I slid backwards down the hill. And I didn't get very far up the hill to begin with. I never found the flat terrain - just kept spinning over and over and over.
