Wynguard Army from Wynguard Palace Landmark is showing the wrong population.
Wynguard Army consists of 2 Spearmen, 2 Crossbowmen, and 1 Trebuchet. This comes out to a population of 6.
Currently It still shows the old value of 7 instead of 6 since Trebuchet got their population reduced from 3 to 2.
This can lead to a population block if you have only 6 free population left.
