Operators and forklifts with dispatcher

I have a problem: I’m working on a case where I need to simulate a picking system. The issue is that my operators (Dispatcher3), who are supposed to store the boxes, do not pick up the boxes from the corresponding queues—or they do so for a while, but then they stop moving. Additionally, my operators responsible for picking (Dispatcher6) only some of them move, while others remain idle throughout the entire simulation. I don’t know why this happens.

Another issue is that my operators using the "Armado de producto" machines (5 machines)—only 2 out of 3 operators perform their tasks, while one stays idle throughout the simulation. My forklifts (Dispatcher7) also fail to work: of the 2 assigned, only one moves.

Overall, my operators and forklifts (avg and classic) are not moving as expected, which causes queues and eventually halts my simulation on the fourth day.

- The items that stay in the queues simply don't have a rack that accepts them based on the matching label pull requirement.

- The "Racks Selectivos" are either set to use Transporter3 for transport tasks or do not have a task executer reference at all. Hence Transporter 3_2 is never used.

- The same is true for combiners. This leads to only combiner4 actually working which in turn means that there is only ever a single active input transport task and thus only one the TEs connected to Dispatcher6 is working.
