It sounds like you just want to use the “MoveTo” functionality. If you’re doing stuff like patrolling then you probably want to use a Behavior Tree. Inside there is a node called “Move To” as well. Search YouTube for “Patrol AI”. Try following one or two tutorials. The project(s) you create from them may not be usable in your main project but they will give you some exercise with the AI features. If you use them to their fullest then you won’t be wasting time/energy/CPU/etc to reinvent something they already do for you.
As far as your timeline issue, that’s pretty darn weird. If you feel you must do it this way then I can try to look into it further, but it doesn’t matter what your track is doing in the timeline. It’s the length of the timeline that determines when Finished gets triggered. It looks like you have it set to 5s, so I find your issue very strange.
