I've started using ProcessFlow. I made it so that the operator loads items from queue and unloads them on task executer. This task executer has a model of a trolley I've made in SketchUp.
The problem is, that when he unloads on that trolley, the items appear not where I'd want them to. I've tried using setloc commands in both operator's and trolleys OnLoad/OnUnload triggers, but it doesn't change their location at all.
