Game Cache on Battle.net

I recently (patch 1.13b) tested out game caches on bnet. I made a map where when you type -save it would save your hero in a game cache. The hero would be saved as your name in the game cache. Then when you type your name it would load your hero from the game cache. I tested it with two people and it worked for both of us :). I attached the map so you can test it out too.

Unfortunately, when you leave the game, the game cache gets cleared, so it doesn't work...

Sucks doesn't it.
