List of Bugs I've Experienced

[Dantius III]

- On occasion, when I use a great scientist or whatever to discover a technology that founds a religion, it does not give me a holy city and the religion is not established. Then turns later someone else gets credit for discovering the religion.

- When I switch a wonder production to something else, turns later when the wonder is built by someone else I will get money for "lost production" even though I had switched production of the wonder ages ago.

There were a few others that I'm forgetting, all minor things really in an otherwise great game.

This isn't a bug. When you change production, the shields you've accumulated stay with you in case you want to return to the wonder. When someone completes the wonder, you are reimbursed for the shields you have accumulated.

Say, you want to build Versailles in Rome and halfway you want to change it to the Spiral Minaret, you don't loose your hammers. If you succesfully build Versailles in another Roman city, you get your hammers from Versailles in Rome as well!

I've experienced something similar to the first one when I get a religious tech from the Oracle. Usually I get the religion, but not until a turn or two after I get the tech from the wonder. I've no idea what would happen if someone else discovered the tech in the intervening time.

The second one isn't a bug. You still have stored production on the wonder in case you want to switch back. It's only converted into cash when you can't switch back, i.e. someone else has built it.

I used to use the trick of producing an expensive building while researching a tech. Once tech was researched, I would change production to a newly available wonder, etc. and my production units would shift to that item.

Now the shields (hammers) are not applied to the changed unit. Is this really desired?

Absolutely. This of course, has been a major exploit in Civ since the original. It takes care of the exploit, as well as making construction more realistic - I mean could you really almost build the great wall and then at the last second switch it to The statue of liberty

But realism aside (and I don't much care if the game is realistic or not) it adds a great game-play issue: that is, you must actually think before you build. Each building decision is very important and that is what the big theme of Civ 4 is: interesting decisions. Also this eliminates the cursed "wonder cascade" from Civ 3 where as soon as someone built a wonder, each AI civ would switch to the next wonder and about 5-6 wonders might be built within a few turns.
