For those who have been here for several months, that 3-character captcha is not as worrying because we've seen it happen before without consequence. It's just a weird little glitch, but it's not dangerous. If you refresh the login page, you'll get a captcha of normal length. As long as the url is correct (silkroadvb5piz3r.onion) and you are not being asked for your PIN, then you're fine. Also - before anyone brings it up here (as it's already all over the forums) - YES, there are delays in bitcoin deposits! DPR is aware of these issues.
