Yes, but did the designer say he will rework the plans, because
a) he claims that the crescent was a coincidence and he doesn't really agree that it shouldn't be there (the "designer" presumably didn't know that the crescent if a symbol of Islam like the cross is for Christianity)?
b) he claims that the crescent was a coincidence and he now agrees that it shouldn't be there (same note applies)?
c) he knows of the symbolism and wanted the symbolism to appease the terrorists and gives in the pressure now?
d) he knows of the symbolism and is now convinced that it would be wrong to appease the terrorists?
