Bugs

 * Should you send a companion to a settlement and make them permanently hostile, with Danse and X6-88 being examples, they will remain in the settlement you sent them to and are unable to be killed. Though they will not attack the settlers they will attack you when you approach them. Currently there are no patches or fixes to this bug.
