We are in complete agreement as to one cache/one happy face. However, here's a few caches we claimed double for (and took some heat on) because the single cache page was split into multiple caches, all with their own coordinates listed, each with it's own log book and trades, and none of them required you to find one in order to find the other(s).

The last one was made up of two new caches and three older caches, combined into another, separate cache---Even though the older three caches still exist with their own GC#'s. (We had already found those previously, so didn't claim them again
