You need to clarify what exactly the error is. I can see three potential errors that may be addressing: One, you are reporting that the building next to the lumberjack is cutting into the trees. Two, you are reporting that the lumberjack is small. Or maybe you are saying how his arm is going really far inside his shoulder. In the former case where the building cuts into the forest, well, that is only going to be changed by having the building to be at least one more size value. In the second case where the lumberjack is a midget, which I think is what you mean, that is a small error that is not worth redoing the anim. I never noticed it, but if it bothers you unduly, then by all means, get his blend and redo the anim. And in the last case, you need to know that this happens in tech, too, just like how the the swordman's blade goes through his head in tech. And in any case, I would say simply relax and pretend you never saw it, because these are not major errors.
