What happens if you and mate both have same tree and he is in your world? Read answer below.
Trees in Coop
Once you’ve claimed a tree you can move it to any of the other trees and yourbuildings and everything will be moved to that tree, you can’t claim the same tree but you can set it to where they can build on your claimed tree by making the tree public.
Otherwise you can just claim two separate trees independently of each other and build your own bases.
Tree bases can be moved to other unclaimed trees and follow your character wherever you play it. You can build wherever you want in the wild, just can’t take them with you.
There are a few safe places to build for a rest stop. Like on the Owl Statue stump or in front of Lisandra’s door.
