Looking through cookies, I narrowed it down to google.com cookie. Deleting google.com cookie will boot you out of your account but it fixes things like before. For me there are at least 17 google.com cookies for every login, specifically the SAPISID google cookie is the culprit I could find thus far but unfortunately this is tied to account stuff so I can't disable it
