Hi,

Thanks for all your help building this awesome tool!

I'm currently having issues using pybpod to trigger state changes using a counter threshold.

MRE below:

def get_state_machine_trial(self, i):

        sma = StateMachine(self.bpod)
        sma.set_global_timer(1, 10)

        sma.set_global_counter(counter_number=1, target_event="Port1In", threshold=5)

        sma.add_state(
            state_name="trial_start",
            state_timer=0,
            state_change_conditions={"Tup": "wait_for_lick"},
            output_actions=[
                ("GlobalTimerTrig", 1),
            ],
        )

        sma.add_state(
            state_name="wait_for_lick",
            state_change_conditions={
                "GlobalCounter1_End": "reset_counter",
                "GlobalTimer1_End": "exit",
            },
        )

        sma.add_state(
            state_name="reset_counter",
            state_timer=0.1,
            state_change_conditions={
                "Tup": "wait_for_lick",
            },
            output_actions=[(Bpod.OutputChannels.GlobalCounterReset, 1)],
        )

        return sma

If i understand correctly, 5 'Port1In' events should trigger the state change from 'wait_for_lick' to 'reset_counter'. However this doesn't occur according to the output logs even though the event is detected.

Output log:

Interestingly, when I hook up a state following the counter trigger (such as 'reset_counter' in this case) to something external like opening a solenoid, I can hear the solenoid opening, but the logs look the same as the above (with the solenoid opening state start time as NaN). This implies a weird behavior where the state is reached but its start time is not logged and remains as NaN.

Any help you're able to provide would be much appreciated!
