The crewmovement.lua file has now had the closedoors() function commented out, which now appears to prevent all door closing activilty by crew. I had left this function alone before as I thoyght it was to do with pathing but I realised that it also caused them to look for open dors and close them.

Adds a new script called crewmovement.lua, and patches all crew related .behavior files to use this instead of the vanilla movement.lua. The difference in crewmovement.lua is that the call for the closedoorsbehind() function has been removed, thus preventing crew from closing doors. Mostly.
