Strange Repetitive Error

http://imgur.com/a/5pjWZ

This error shows up during the loading of my project. I can click any one of the buttons and every time, the error message just goes away and it keeps on loading. This same error shows up 5 or 6 times towards the end of the loading, and has only just started doing this ever since I moved my project off of the C drive and onto the D drive and moved the GI Cache location similarly. Because this was on 5.41, I updated to 5.4.2 and nothing has changed regarding the error.

I don't notice any negative impact this has besides slowing down my initial launch of Unity, but is this something I should be worried about? If it's possible to fix, I'd like to do that regardless.
