Anyone else can't log into mechanic?

If you've been turning in red envelopes, your inventory may have been glitched like this guy's.

I don't know if his problem affected his ability to log in, but it would explain why you had trouble picking up items.

Indeed i did return envelopes and had no space when i was supposed to get the cs item. Exactly like this guy you linked. Still, why i can't log in is real mystery.
@sapta I get the same message as your guildie. Will try again now and report.

edit: Nope, still can't log into mech.
