Even though I checked via console that the local var signed_in is indeed set to 1.
The only possible explanation why the marked events are skipped is that the variables checks return false.
I'm not sure if you can use "Wait for previous action" to wait for the script to finish executing. My guess is that it just waits one tick and continues running other events, while logged_in value is still 0.
I would suggest adding Browser Log after "Wait for previous action" action to check the value of logged_in variable.
