It's not my map, I just want to know why this might have happened.
It's a little odd.

Sometimes payloads do that, very rarely. I think I've seen it on almost every map with a cart, actually.

Yeah I saw that once on Badwater. Cart stayed with its nose pointing up in the air until it started reversing.

I'm guessing it has something to do with being right on a path node. Probably nothing fixable.
