Preventing Startopia visitors from walking in circles

Just after I took over an AI player's territory in Startopia sandbox mode, my visitors started walking themselves to the point of death or desertion.

They walk to the end of a line, then turn around and go back. The bunch by the roulette wheel does not move at all.

Does anyone know why this might happen or how it might be reversed? I've thought of bombing them and have already removed some nearby security columns to clear their way.

Solution 1:

Remove the duplicate buildings.

Then make sure that everyone's basic needs can be meet (hygiene, food).

You may need to rebuild and reorganize a lot of rooms and hire aliens to operate them. This is typical if you have a lot of new aliens to look after now that you've defeated the AI.

Also, the visitors often get "stuck" when they want to go to a different manager's section and they cannot travel there. Trying to take over another section (above or below) will often get theses aliens moving, as they can finally path to where they want to go while a section door is open between your part of the station and the other manager's sections. Unless you are rolling across the entire level, you will often "lose"/anger many of these stuck aliens who cannot reach their desired destination and refuse to chose something suitable in your sections instead.

Solution 2:

Try to remove duplicate buildings. With the possibility to go around the entire station, the AI seems to be overburdened when trying to determine which building of a desired type is the nearest one.
