Wow! I forgot there was even such a thing as flea market purchases!
I added fight.php - complete with comment about Marmot - to that list of URLs in revision 9378 on June 1, 2011, after ascending in the new Marmot sign in order to test it. Before the Valhalla revamp, you did not get a clover after a fight. You got a clover as a result from visiting adventure.php. Now you get it after a fight.This patch adds the flea market to the list in isCloverURL(). It also removes fight.php since marmot works differently now.
