We’ve recently made a switch to a new bug reporting method using a more structured form. Please visit the link below for more details and report the issue using the new Bug Submission Form. Feel free to continue to use this thread for community discussion around the issue.
NavLinkProxies alone won’t allow the AI to bridge the gap between the two NavMeshes. You have to actually have your AI jump the gap. This can be done by using a Box Collision as a trigger, casting to your AI character, and an ‘On Component Begin Overlap’ node. The setup is pretty easy as well.
