Is it even possible to have dinos patrol and harvest on their own? I have been digging tring to find out how it works with little luck
Look at the Doed and the Bigfoot… both harvest while on wander.
What you could do is have them check for resource nodes when set to wander (not sure how to test for that, but I’m sure it’s possible), get the location of said resource, and set that as their target movement location. I would also recommend an option to disable it via the GUI so you don’t have breeding dinos wandering away to harvest.
