Summary

Player Simulator from Integrated Tunnels can give player items via hand over your items , but when Player Simulator gives an item, such item, usually placed in a chest, will not be consumed.
This causes item dupe, where Player Simulator can give a player the same item for infinite times, as long as the item can be read by Player Simulator.

Steps to reproduce

• build an IntgDyn network. There should be a Player Simulator and an Item Interface attaching to a inventory(chest), also remember to power it.
• open Player Simulator, place an empty Variable Card in the second line. The corresponding operation name is right click .
• click + symbol in the 2nd line, and switch to sneak option, set it to true .
• quit GUI, place anything in placed inventory(chest) .
• stand in front of the Player Simulator.
• Player Simulator will give you items for infinite times.

Solution

I'm perparing a PR to provide fix for this. Will be avaluable soon.
