Attached the vanilla repro, I managed to construct (in this repro switching back and forth didn't "fix" the issue though - seems persistent).

Tested on A3 2.10.149954, no mods, Widows 10.

Repro steps:

1. Run the scenario as EDEN singleplayer preview.
2. At any moment, while the Hunter is struggling with obstacles or prior to that use 0-0-0 keys (Juliet radio channel) to hide nearby map objects.
3. Observe, how Hunter keeps colliding and pay attention to invisible objects around.
4. Optionally use 0-0-1 (alpha radio channel) to unhide the objects.

Example of test:

Happened every time in few tries.

So far I was unable to reproduce this on Stratis (Agia Marina urban area) and Altis (Kavala city) - in both cases as soon objects are hidden, car stops pay attention and collide with them, instead goes straight to the waypoint

Can happen on Altis too, not each try though. Same repro description, but happens about 50/50.
