I know that for an object to be removed from a pallet rack you need "Rack Pick". However, in one of my models, I have a different configuration where I am using pick up:
Step 1: 10 agents are in the rack
Step 2: Another agent picks them up
The way AnyLogic understands the above is that the rack still holds 10 agents, so I get the error eventually that the pallet rack is full. Is there a simple turnaround for this?
