"Hide and Seek" Emails
Here I was thinking I hadn't gotten any email since yesterday. Checked the webmail interfaces of Yahoo, Outlook, and Gmail. Emails were there. Found the missing emails (63 total) in the "Junk" folder in Thunderbird. For some reason, the email client sent EVERY email since yesterday to that folder. I marked each email as "Not junk", and now the program seems to be working properly again.
Out of all the years I've used Thunderbird, this is the first time this has happened.
