I am hoping some 1 can clear something up for me... For some reason the past couple of weeks when I enter a fellow COA members city in response to them being attacked, I can't assist in repairing their towers. There are not any of those hammer icons which you usually press to initiate construction and when I place the cursor over the "building" nothing happens. Anyone have this happen to them in the past or have heard about it happening to someone else? If so & there is something I am doing wrong (although I can't imagine what it could be) please get back to me.
