If a pest control EMG service tries to leave a Island map (not connected) While a visitor boat/Helicopter isn't already docked and waiting for people, it breaks all boats and helicopters making the helicopters spawn into the map, fly over the helipads then go off the map (and infinitely repeat) And boats Just get stuck at the edge of the map.
I'd suggest the developers fix this Game breaking bug
