I have no idea why this is happening, but I would like a final answer to what I can do about a problem I have been having for a VERY long time now. Quite simply, New Vegas keeps needing me to reacquire files. I can verify files and steam will think I need to reacquire 3.8 GB worth of files. If I IMMEDIATELY ask steam to reacquire files again - not even launching the game, it will say I need to reacquire 5 GB of files. (These are 2 real world examples.) Aside from the numerous problems I have been having with New Vegas modwise, I would really like this fixed up. Thank you in advance for any help or suggestions.
