srosaxcii: I'm currently in the third level and when I reached London I started exploring and noticed that only four chests yield a special bonus. After that all the others are empty though the fanfare still plays if you open them. Is it a bug?
I do not remember the specific mission but in Cultures 2 you will find chests that contain only 1 potion and place it right next to the chest so sometimes it is hard to see and some chests will contain no physical goods but the notice that you now can build a building for free.
