not sure why that would be the case. I also use some custom MoveTo nodes, so I’m not sure what the difference might be (it might be possible that the default MoveTo actually doesn’t allow the abort to succeed… I have used a little trick like ignoring an abort request in a task, so that i can be 100% sure that my task actually completes …)
Your Tick in that blueprint does exactly the same thing as the Acceptance Radius parameter in MoveTo
