Tournament Arc

Tournament Arc was my second puzzle hunt, and with the help of some friends was significantly larger than the first. You can find it here.

It contains 18 puzzles and a metapuzzle.

Unfortunately, several of the puzzles are now unsolvable thanks to relying on knowledge specific to my college.
The following features suffer from this problem:

• Coffee Break - The campus Coffee Cart served all the coffees this puzzle references. It should still be solvable, just more difficult (I'm relatively sure most of these coffees are standard).
• The Best Friend - This puzzle references group themes, as hidden in each group was a letter attached to some object or piece of furniture.
