This thing happened to me when i used the G button to activate the jump feature (High gravity Jump Zombie), however, the CT froze me after the freezing ended, I found the feature still on although the cooldown is finished,
I know it's a rare case where it needs specific activity to enable, however, if people discover it, they will abuse it, so it's definitely harmful and annoying in the long term.
