In my case i had about 20 Darwinians dancing in circles on the beach by the machine and dish. No matter what i did with officers, they ignored them. To round them up i had to tediously turn them all into officers and order them to the compound. I've noted other stragglers that don't respond to officers.

When Darwinians are given an order, they will continue trying to fulfill that order forever. This means that if you try to direct them into a building they can't go to, or somewhere else they can't go, they'll end up getting stuck there.

The simplest solution to fix this is to just go to the map and then back to the level. When you do this, they should all be just milling around in the area they had been stuck at. They can then be rounded up by officers.
