ObjectFunction246 exception error

[stayhometown]

Hi everyone,

My model encountered this exception error, but it can still keep running, so I’m not sure what exactly is wrong.
I checked the event list viewer, and I wonder if it’s related to those “no path” issues that are causing the error.
Where should I start looking in order to fix the problem?

Since the model file is too large, I’ve attached the system console error log, the event list viewer, and the possibly related process flow.

Most commonly this happens because an item is removed from a processor before the process has finished, but the event is not removed. When the event eventually fires the missing item is causing the error. In your Process Flow you use a Delay activity to wait for the process to finish. Even if the process time and delay are the same, floating point inaccuracies might cause an issue. You should always use a Wait for Event activity (wait for Process Finish event involving the item) to sync the Process Flow to the 3d model. To be safe, add a "Breathe" activity after the Wait for Event, so you can be sure that the processor has finished all internal logic before you load the item.
