Keep having to re-reference same parts in large assembly

i'm working with decently large assemblies, and the engineer i'm working with used pack-and-go to take the assembly home and work on it. once copied back over to our server i fixed all the references and it opened up fine. problem is that everytime i go back to open the assembly, i have to fix the references for the exact same couple parts every single time. the files that are messed up are located in the same folders as other parts in the assembly. any ideas?
