Fatal error in GC: Too many hash sections and too many root sets?

I can work on my project for a few hours, and I'll get the too many root sets error, which isn't too bad, since it's not that often. Recently(after I imported a unitypackage to look at it's scripts, then everything in my project got messed up for no reason, so I created a new project and recreated my scripts and prefabs a few days ago), I started getting the error "too many hash sections" if I click at all when in the game window, or click the play to test in-editor 3 times(on the 3rd time EVERY time). What is there possibly to do to fix this besides running OSX(if that)?
