When you build the object at 6:51 (https://www.youtube.com/watch?v=V6ugspKOkkk) a tightrope is supposed to appear.

The only thing that appears for me is the anchor the rope is attached to, but there's no rope.

I already have VSnyc enabled because I couldn't move the cart in the first level of the game, and I've verified the integrity of the game's files.

I'm at my wit's end with this game.

EDIT: I completely forgot that I had to built an anchor on the other side of the room. I'm leaving this post up in case anyone experiences a similarly stupid lapse of judgement.
