We will be pushing a patch live tomorrow. Players will be required to log in to Destiny again after returning to the title screen to install the patch. You should not be removed from any activities you are currently in.
Hypothetically, if at any point in the Destiny story line, the Fallen offered to help you kick Hive/Cabal/Vex tail, would you accept their help?
Personally I'm not so sure, they seem a little deceitful.
