Sorry to hear that but I can understand the decision. Keep up the good work.
If you hit the freeze timer option again it unfreezes the timer and allows the game to continue. It's the same way with the Mayhem and other destruction minigames. Once you attain the gold score, disable the freeze timer option and it will complete the round.
The option must be disabled during any countdown and enabled afterward. This means you need to disable and reenable the option between fight club rounds too.
i am sorry to hear that too.. its amazing how some people always ruin it for people like us that apppreciate the awesome work CH does!
I'd like to think this has nothing to do with people giving feedback about some timers not entirely working. Rather, I suspect, since these timers don't work universally (different events having different code), that they decided it's easier just to remove them altogether, instead of dealing with the confusion of having them work only sometimes.
