Help!!! As I saw there are more people who have the same problem as me. In Lightning Bluff I have completed all tasks except for defeating those goons hired by mr wong. The problem is just that there are no goons on my map. I have blown away all trees and no one was hiding behind it. SO the big problem is I can never p this level because there are no goons to find!Just to check: goons are some sort of bandits right? ( im from holland so im not sure, but my dictionary confirmed something like that).
Anyway if anyone can helpme please do so!!!!
