Oh .. I do feel your pain... having done the same thing on more than one occasion.... Redo/resew the block that is out of its proper position. It make take some time , but it will be less than the time you will be reminded of this mistake by leaving it .
When I find myself in this position and so.. want to just leave it ! I have to tell myself even if it takes 8 hours thats is less than the lifetime of looking at it and knowing the mistake is there. But I am compulsive that way ...
Your quilt is beautiful!
