:Please remember, that all those points are removed when you delete a Great Building. This means that also points for goods spent to put it into your city will be removed, when you remove your Great Building.
==[[File:Rank10.png]] 'Inaccurate' math==
This can happen, that the amount of points you have is not an integer. For example: if you have 100 points and you donated 3 of rubber to your guild treasury, you will have 116.5 points - rubber is a good from the Industrial age, so it's worth 5.5 points, therefore your donation is worth 3*5.5=16.5. Even though you have 116.5 points, the game still shows 116. The reason for that is that we decided to simply chop off the fractions when displaying them, as it's technically easier than doing mathematically correct rounding (plus it doesn't use any server power and is far less error-prone). Of course an accurate number is still stored in the database, so your 0.5 point is not lost and as soon as you get the other 0.5, it will be displayed correctly.
