Unit stopping prematurely when using funnel

Let me start off by showing a screenshot:

In the screenshot you will see where along the path my unit got stuck. At this point it just came to an immediate stop.
It does not always do that, I would estimate that my unit stops prematurely about 40 % of the time. Is there any reason anyone could think of why that could possibly happen? ive been over my code and I cant detect anything that might cause this, and Im pretty confident the issue is not in my code, although I could be mistaken of course.

Has anyone run into similar problems or has any clue as to what might be going on here?

Thanks in advance.

Actually fixed it. Thanks for checking anyway.
