Basic Conveyor Problem

Hi I have a problem with the Basic Conveyor
On the Picture you see that the 3 Decision Points on the horizontal Conveyor are fired. but on the 3 Point there is no item. With the code getitemrank() i found out that the yellow marked item fires the Decision Point!!! furthermore there is this Message in the Systemconsole:

createvent: event time is in past: event time changed to present. Object: maincon03 advancetime: -8.226523, clock: 490.500923 Product

thanks in advance for your reply

Hello Michael,

maybe you move a item in a previous decision point from the conveyor. The event still exists on the 3. point. All events are calculated, when a flowitem enters a conveyor. If you do something different than the standard behaviour, then the conveyor behave strange. You have to look yourself for a method to correct the conveyor event list.
