Tropico 4 / MT - need help with mission 6

[Venatacia]

Hello, I'm stuck on mission 6 - Keep calm & Carry On. I seem to be missing what the mission is about. It says keep above 200 I think but how and what do I need to do please ?.

Build your canary to compete that export 500 cans mission.

Fire everyone in the canary and close the job slots. The U.S should beg for more goods. Wait for the CGI to go up around 300 then open your Canary again.

Next, open the Canary to complete the mission to export 30,000 worth of caned goods.

There is a bug that won't allow you to continue if you build industry to fast. Normally it just ends in mission over.

That bug is still there. I exported 30,000 befor the cgi goes up to 300 and instnatly get a fail.

JC you follow the work around posted above to get past the bug?
It is annoying, but the Work around does work. I had to also use it.

@omnix32: I did get past the bug using basically the idea of posted work around. Here is the detail:
I first finished exporting 500 canned goods. Then I was instructed to keep the cgi to be at least 200 fro some period of time (48 months? cant remember )and almost at the same time receiving the msg saying "making $30,000 from exporting canned goods awards extra 300 cgi". So I fire all workers in the canned goods factory, and just wait until the cgi rises to 300. It is true that the cgi will increase at first but then I find it may go down from time to time later. I then reopen the factory and gain 30,000 profit, and keep finishing secondary missions that also increase cgi. Finally that specific objective is accomplished.
I cant really find out game instructions that how to keep cgi to be high. I can only suspect based on intuition that the less the supply, the higher the price, and the higher the cgi and level of chaos. So another issue here is the side missions given at the same time.
