Hey SirHarryPierce, thanks for reaching out and bringing this to our attention.
I've had a closer look however it does not appear that this has been brought up before, therefore is there any chance you could provide us with your save file for reproduction purposes? You should be able to locate it in %userprofile%\Documents\Anno 1800\accounts
Let us know!
