If you didn't receive the resources or if your cargo has not been upgraded, please make sure that you have at least 500 empty storage space for each type of cargo
before applying these Resources Packs. For instance, if you have 1000 Max Sugar Capacity, check if you don't currently have more than 500 Sugar in your storage.
Also, please note that these Resources Pack will not be available before reaching at least Sequence 4
on your current playthrough of Assassin's Creed 4: Black Flag.
