If you need to quickly produce several items in one production building, but the production queue is full, it is possible to rent production slots.
To do this, click on + in the
production queue.
You need c-coins to rent a production slot.
The rented slot will be available for the duration of the rental. The rent timer in the form of a progress line is displayed around the rented slot. After the rent time expires, the slot is no longer available.
If the rental time ends before the production end time, the slot will be displayed until you collect the produced item, after which it will become unavailable and can be rented again.
