视角向上移动到一定位置后就无法移动，导致无法点击到设施

This Achievement description says obtain a balloon so how do you get this balloon ? My guess is that you get it somehow from that pilot flying the blimp that visits our airport but an elaborate description of how to get this would be nice if somebody could leave it for us...

The screen refuses to go to the bottom of the map where the dock wants to be placed. How do I scroll to that area to place the dock? I have tried saving and quitting multiple times, still cannot get the center of the screen to scroll to that portion to place the dock....

I have connected all of the worlds but I still don't have it.

I am unable to see robbers. I have never caught a robber. When the message pops up about robber in the airport I literally pause and scan the entire airport pixel by pixel, inspecting every single person, and I simply cannot see any robbers! I know what they are supposed to look like but I literally cannot see them! Is this a bug where they become invisible or somehow have a wrong sprite? I literally cannot see them!...
