This really isn’t that big of a deal, but I like to check my times after completing a level, since that feature is available. Only, I completed The Library about an hour ago, and I came to check my time here and it says “20 hours, 19 minutes, 23 seconds” which is clearly not correct. I played to the point yesterday where I was waiting for Guilty Spark to open the second door, but had to Save & Quit and resume the level today. I ended up restarting the level because I got myself stuck in a bad spot last night with, in a corner with an army of Flood in of me.
Just a weird little glitch that should be known about.
