So I was working on a project for about an hour to two hours, and I realized I hadn't saved since the first 10 minutes. I went to save and it just had a loading bar and said saving... For a really long amount of time, literally about 45 minutes. My computer then froze, and I rebooted it. Nothing was saved, so I re did some things like animations that took like 5 minutes now, and then I tried saving. Nothing, and it currently STILL isn't saving. It's been about 7 minutes already.
