Another (more minor) bug that probably doesn't need a whole bugfix version: When on Astra quest 4, you can talk to Layla about going to see Astra, but when you try to talk to Lisa about going again, you get an exception due to label ask_lisa_about_astra_2 not existing. It's not a breaking bug since the quest continues when you talk to Astra, but that choice should be removed or that label should be added.
