The release of Districts 4 and 5 unlock levels 5 & 6 of the Pasaporte Office Property. This is probably the most useless property because by the time it’s upgraded you no longer need the consumables. If you do need them you can’t make enough of them to notice a difference. The chart below is revised from the one made in the original post. This property is unique in that the upgrade process is halted between the release of new districts. There are 4 more levels to go and most likely 2 will unlock at a time. This always causes confusion as many think it’s a bug because they can’t upgrade any further. For now, 3 stars (6 levels) is as far as you can go. From the levels confirmed you can see the pattern and it will most likely require 360 parts to fully upgrade this property to level 10 but we won't know for sure until the last 4 levels unlock. More details are shown below and the information for Levels 0-4 can be found here.
Level 5 (2 and a half Stars) unlocks the District 4 consumables and Level 6 (3 Stars) unlocks the consumables of District 5. You can make up to 3 items from any of the 10 available every 18 hours once you upgrade to to highest level.
Zynga cracks me up with properties like this because you have the option to speed up the timer to make 3 more items for 12 reward points but in the Marketplace you can buy 2 items for only 1 reward point. They really need to revise this property to make it more realistic. It would be more useful if we could make about 20 items every 8 hours or something along that line. For now most will ignore this property and it will be the last to be updated. Once updated it will rarely be used because players will no longer need the consumables.
