Based on the fact I can demolish any other upgrade on my walls and there's nothing in-game to indicate that it's a permanent choice, it made it appear to be a bug.
yea i think you should be able to Change it. the System is implemented like that. you can destroy/demolish the unit and rebuild something diffrent. i dont see a reason why your being forced to use something. specialy if you make a mistake which we all did in the beginning your will be punished? we can also reset exp pts
also i might add that with me it only happens to the gates and 1 wall, the rest of the walls i was able to upgrade perfectly. so it must be a bug.
