The algorithm for selecting players for head to head matches for coin games to frequently goes into a loop where it cannot decide who to select as your opponent. I have waited over 20 minutes for it to make a selection with no results in the Tokyo room with over 100 p[layers playing one hole games that turn over every 6-8 minutes. The algorithm needs to have a time limit that after 3-4 minutes it stops trying to use whatever parameters in its code and just switch to next available player.
