the menu option "Talk to the schoolgirl looking at her phone" (map_tampula.rpy:279) is never locked, even after the MC knows her and she wants to get paid for sex (the "Talk to Moltena" option a few lines later).
I think you should use as condition "if tampula_miscquest_available1 == True and clock.time_of_day[0] == "Night" and tampula_miscquest_progress1 < 2" to close this one when the other option becomes available
