Fast reactions not being collected
I'm looping stimuli in quick succession (~2 Hz) until the participant responds, and then another loop begins. For some reason, when the response comes (almost) immediately with the next stimulus in the same sequence - it is not being collected (essentially ignored and the trial continues as if nothing happened). This happens both on the normal OpenSesame platform and on OSWeb (in which the experiment is intended to run on when collecting data).
Apart from a short black screen and a fixation point, each trial involves a stimulus follow by an inter-trial-interval. The participant is able to respond during both of these. Both durations are set to '0' followed by a keyboard component.
It feels like I might be missing something very trivial, but I don't know what exactly and would appreciate your help.
I can't upload the experiment directly since the file is too large but it is available through the following link:
