sponsor's address i 864 and i 865

Hello, I have a rather complicated problem.regarding sponsor's address. When we filed the i-864, sponsor had already moved to a new address, but we just went with his old address(we didn't think that address was important). Now, my immigrant visa is issued and I am going to the US next month. Would this be a problem at port of entry? Will they find out that sponsor's address now is different from what i wrote on i 864? If this is the problem, i will have to file foer i 865, but i worry that this will cause even more problem, because move in date is before the date sponsor signed for i 864, which indicates that we willfully put wrong information on i 864. What should i do? Should i just go to the US without filing for i 865 because they won' know about the sponsor address change?
