help and possible bug

[ronin]

I am playing on medium difficulty for my first game and I have had the manager on for some time now. Is it me or does this game give way more pollution than is possible I am at about 2370 bc and have just invented conservation and my pollution is out rages I am developing dead tiles around my cities. Also I have hospital and aqueducts and every thing up to this point for increasing size of cities I have total of 26 cities. There are 9 at 32 and 11 more at 31 and 5 at 14-29 and one at 7 what else can I do to help my 32 cities grow beyond 32. The great library states that aqueducts and hospitals increase city size but combined do they only go to 32 or is there something else I need to do. Now the bug part I put a corporate branch unit on cargo helicopter and it was on the heicopter and yet it was not the chopper said it was on it but it still was in the square for about 10 turns even after I let it out on diferent island any one else run in to this. any help on the above would be much appreciated.

1. You'll need Arcologies to get past 32 and Aqua-Filters to get past 46.

2. You can't run your cities flat out if you play with Pollution on. Convert citizens to non-Laborer specialists to get pollution to 400 or less. Press F2 and check the National Manager to see which cities need this. You'll probably need to do it every turn. (Yeah, it's tedious.)

3. Don't understand about the chopper. Sorry.
