Hello, I am encountering a strange behavior in my simulation. It appears as if an event triggered source is only working once. I have created an event triggered source which will start a cleaning process when a gurney's output is changed (i.e. when a patient leaves the gurney). I have attached a screenshot of the source and I have attached my model. For gurney 1, it works perfectly as the HCA cleans the gurney when patient one leaves at 9:04. However, when patient 4 leaves at 11:20, it doesn't work, and it also doesn't work when patient 7 leaves. This problem also happens for gurney 2, when it works for patient 2 but not patient 5, and for gurney 3, when it works for patient 3 but not patient 6. I am pretty confused as to why it works at first but not for any additional patients, so any help would be much appreciated. Thank you!
