I calulated my culture building. I have culture 2478 points but its show just only 1930.
I tried to place Luminous Signpost +21 but it gave me just +1.
Hi @Phipake, it would be extremely helpful if you could take a screen shot of your Culture Points before and after placing your Signpost. If you could do that and place it here in the comments, we can have a look at what's happening
Not sure this is still happening, but it used to happen that when you place an event building you get some bonus when you place the building and another after 10 seconds when it finishes constructing. You had to add both to get the final number.
