One important thing to remember is that some caches are ‘swap/treasure boxes’. If you remove something, you must replace it with something of equivalent value. Some of these boxes also contain trackables, which can be various items with numbers/letters on. These are not treasure/swaps, but items/tokens that travel/are moved from cache to cache.
