random but important question - if i have a contenent full of jungle - and i clear it all down to grassland before i discover rubber - will any rubber appear where there used to be jungle? should you not clear jungle untill you discover rubber, so that you don't lose the resource if it is there, but undiscovered? has anyone cleared jungle, discovered rubber, and then found rubber where the jungle used to be? otherwise, it would make sense not to clear jungles until you have determined wether rubber is on them-
