Getting logged out of admin area when refreshing site
The problem was actually Chrome using iOS emulation when viewing the site, thus spoofing the UA string into something different than the usual Chrome UA string when logging into the admin area.

Solution (as suggested by @craftcms on Twitter) was to set:

'requireMatchingUserAgentForSession' =&gt; false


In

craft/config/general.php


For whatever environment you are having the issue.
