Conveyor output more items than processor capacity

Hello,

In linked model, somehow the conveyor exit transfer may send too many items to processor.

Send To Port = First Available

Processor Capacity = 1

Filename in FlexSim Cloud = "Conveyor output more items than processor capacity.fsm"

FlexSim 22.2.0

This is a bug with the ExitTransfer when it has multiple output ports and the "Stop at End" box is cleared.

The nroftransportsin variable of the downstream objects is not being updated correctly when an item that was scheduled to be transported passes the end of the transfer and cancels its transport.

I've fixed it for the next 22.0 and 22.2 bugfix releases.

If you want to work around it in the meantime, you'd need to use one ExitTransfer for each downstream object and write your own availability logic in the decision point's Send Item logic instead of using the built-in send to port First Available logic.
