Exception when resuming an AGV which was stopped during offset travel

One of our customers added a MTBF/MTTR to their AGV model and found an issue with the new offset travel functionality.

It seems that stopping an AGV (with stopobject) at any point during an offset travel operation causes an exception to be thrown within resumeobject when you later try to resume it.

The attached model demonstrates this issue 14 seconds into the run.

For now I've got the customer's model running again by handling the offsets manually (as normal travel operations) in process flow, but I'd love a simpler workaround if you happen to find one.

Yeah, this looks like a bug. I'll add a case to the dev list.

We seem to have overlooked this question.

@ allister.wilson You have used pickup point connection in you model that is not been referred anywhere that cause error in you model when AGV reach the pickup point. Normally the Pickup point connection are used when your model has more than one pickup point option. When you used the connection you should commend the AGV by process flow or by network properties to look for the available pickup point.

I have attached the modified model for your reference have a look at it
