Touché, I did not catch that sentence inside your post, I got hung up on the suggestion that EB move to the Alexander expansion and your sarcastic tone throughout this thread. I apologize for reacting with exasperation when you did in fact concede the point.

Bugs are expensive to remove. They require many hours of searching for the error. Any commercial venture will only remove those bugs that are bad enough to be cost-effective to do something with. CA have removed the major bugs. What is left is stuff that they themselves don't use (a fact which is a great obstacle for modders who would want to use it, but nothing they are obligated to support), or affects too few people or in such a small way that it will not affect their sales of the game or their reputation very much, like your problem. Also, they will not get much revenue from RTW anymore, as it's old and superceded by M2TW.

The fact that so many have bought RTW, BI and M2TW is proof that the bugs in their products have not been enough to lose faith in them. They have thus made sound financial judgements.
