I don’t think it really fixes this issue, but it looks less problematic that way.
Are you referring to the confusion over how R2 got the map in the first place? Because I agree that this doesn’t attempt to answer that question. This edit only attempts to fix the plot convenience of having R2 wake up at the end of the movie for no apparent reason. The fact that R2 probably has over 80 years of backup data helps explain why it would take him several hours to search it.
