Duck traps are made in Net Maker, and like other production machine, it can make as many items as the machine’s table can hold before the production queue is full. The item that is put in production first, will be the first item to be ready and all other items will come after it. If you have many finished items sitting on your Net Maker’s production table, you will need to collect those items before you can collect the last recent item you made.
For example:
You have 8 ready mystery nets and 2 lobster traps waiting to be collected from your Net Maker, and the last item you made was a duck trap. Before you can collect the duck trap you will need to clear the mystery nets and lobster traps before collecting the duck trap.
These items are stored in the Tackle Box. Make sure you have enough space in your Tackle Box for all the fishing equipment you are making, by constantly using the older items, in order to make room for you to use the newer items made.
