When I noticed the changes in the TA I contacted Roy via email. He said I should post what I experienced in the "Bug" forum. I did, but it was moved here by Skuzzy.
I wish Skuzzy had replied that the changes were necessary or that corrections needed to be made. Unlike the MA the buildings reset (rebuilt) after a few minutes before the update. I wasn't aware that anyone had ever taken a town in the TA.
Not being able to "blow things up" as we had before has two down sides. One is that I can no longer tell what I hit in the radar site or town so accuracy assesment (BDA) is no longer possible. Secondly, what fun is there in hitting "indestructable" buildings?
Well, the good news is that I can practice on RR bridges for accuracy and, as of yesterday, the buildings off line do blow up. (Trouble is, the Ack works there too.)
