AGV Not Picking

AGV-Question.fsm Can someone tell me what I am doing wrong? The AGV will frequently pass through a pickup point with a part ready but not load. Eventually it will circle back around and load.

When you have more than one outgoing NextWorkPoint connection from a CP, then the AGV will alternate between them. At 225s AMR_2 is send from point 1 to point 2 in the screenshot below. Until it arrives there, it will not check any other CP it passes along the way for work. Only when it passes poitn 1 again will it drive to point 3 afterwards and actually check if there is something to load.

It doesn't really make sense to have a connection from 1 to 2 in this case, because the vehicles can't turn at this intersection as there is not transfer point between the paths. The NextWorkPoint connection should instead go from the CP to the left of 1 directly to 2.

Furthermore, you can prevent AGVs from taking unnecessary detours by using WorkForwarding connections. These 'attach' a pending transport request to a different CP then the one where the item needs to be picked up. You can connect the CPs at the combiners to those on the top path. AGVs will then only turn toward combiners 2 and 3 if there is work there.
