It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

so, on a bounty, reach a vault, go do the next bit and get the 4 digit code <password> from a lackey, cap'n says 'keep <password> in mind when you go back to the vault'

all instances of this code are <password> and i cannot enter <password> on a 4 digit lock.
Are you by any chance using a nonstandard language selection?
