I never logged out. I went to MN. It said I had to log in. So, even I thought it was odd since I should be logged in already, I did. I typed in my email address and password. It said error. It said it wasn't allowed.
I closed the page and went on to MN again, I was already logged in. What was that? A bit spooked, tbh. Never happened to me before, since I joined MN around 2015.
