Basically this morning you only have 1 to 2 seconds to run the sequence otherwise it makes you start over on the exercise even though the timer on the bottom keeps moving. So after hitting the 3 key in the 9 key sequencer i have to start over. So Please fix this bug as yesterday i was able to complete many exercises. I did restart my browser, clear my cache, my router everything. Thier is no lag just problems with the QTE system. I already filed a ticket.
