Our town Prestige stucks at 1000, so we can't rank up over rank 7.
I don't know, if this is intended or what exactly is wrong, but once we reached 1000 Prestige no prestige is added anymore.
We have several public buildings that counts each 100 Prestige.
Adding one more don't add 100 to the towns Prestige.
A small house we have on one of our personal claims within the town, it should count 50.
The Storage Bins should not give prestige anymore, that I understand, even it gave in the past 50 each.
But however I count the placed buildings, I never can do the math to 1000.
At the Picture, the two blue marked buildings i added, first the Storage, where we didn't got Prestige, as expected.
Then a second Statue, but again no added Prestige.
The red marked one is the small house, that should count 50.

If I just count the buildings without the blue marked ones and without the storages, it should have 1050 and not 1000.
After building the second Statue, it should have at least 1150.
