ok, i've been running your mesh for 60 minutes now. apart from the fact that it is the worst mesh i have seen in a while (you clearly did not grasp the concept of navigation meshes), it does gather every node. Just to be sure, that is the mesh your bots stop gathering at some point ? If so please make screenshot of the node that is causing this, i can't find it.
