Beforehand: This might be in connection with AREXP-342, but I don't know for sure.

So AI Logistics is broken at the moment because they just leaving the truck behind or just don't do anything and are on the way forever.
I noticed now why: If they are not in render distant or a reasonable proximity, they stop somehow working.

I send a logi ai a short distant route to a harbor but over the Operations menu (At a base far back so I and other players were far away). After a generouse couple of minutes they still didn't got the truck loaded. So I drove there and as I was arriving at the harbor they went the last bit and loaded the truck. This happend on two occurrences, where I arrived they loaded up the truck, while the whole time showing being empty and still on the way.

Also I noticed at 1 occurrence that if I leave operations menu quickly they don't even get into the truck.

Lastly when I was in proximity/could see them at the short supply route (following them) they did a very good job and there were then no problems.
