Not sure what is causing this but having just demonstrated https://actdev.cyipt.bike/abstreet/?--actdev=lcid&--cam=14.95/53.79136/-1.53469&--actdev_scenario=base I noticed that people are not starting their morning commutes in the development location but seemingly anywhere on the map. Any ideas @dabreegster or @natesheehan ? Will check for other areas. This is what I see (note: LCID is roughly in the centre of the map but the highest flows are not emanating from the site):

Also it seems the site boundary is no longer there.
