Like described here Nav Link Proxy SmartLinkReached event caught by wrong Nav Link - #4 by HAF-Blade the wrong NavLinkProxy reference is chosen, when an AI character reaches a SmartLink of a NavLinkProxy.
I’ve created several different NavLinkProxy actors with SmartLink functionality (and no active PointLinks) and in some cases the correct NavLinkProxy reference is chosen for my handling and in some cases it isn’t.
Instead another NavLinkProxy reference is used to execute the actual handling, which leads to completely wrong ai behavior / movement.
