Stuck in Episode 4
 

This hasn't happened to me yet, In fact I haven't needed to see a hint until Episode 4. I am completely and utterly stuck at the high school. I cannot figure out how to get in the tent for Hill Valley of the Past, which is where the hint says the furs are. I can't even interact with it. I've tried to walk into it, click it, walk around it, but nothing. Am I missing something or does the game have a glitch?

Have you already visited Emmett? Complete some other objectives and come back to it. I guarantee that it will open up later.

Puzzles need to be done in order, and, also, this is the wrong forum to get help.
