I wouldnt think that would affect it. I know it can with the buck as he might be just "too fat and lazy to breed". If your buck has performed well it's unfortunate to say that your doe might just "be a wash" as you said. I wish I had more advice for you on that. You could try breeding her again after she kindles and that might stir her reproduction.I guess I should mention I slimmed her down a little before this breeding as well. She was within the weight for her breed standard but did seem “fluffy” weight wise so that could have been affecting.
